  • BASB232 polypeptide(s) polypeptides encoded by them
  • recombinant materials and methods for their production relates to immunogenic compositions and vaccines containing single polypeptide or nucleotides or advantageous combinations thereof.
  • the invention relates to methods for using such polypeptides and polynucleotides for the treatment or prevention of Bordetella infections.
  • the invention relates to diagnostic assays for detecting Bordetella infection
  • Bordetella pertussis is the causative agent for whooping cough, a respiratory disease that can be severe in infants and young children.
  • the clinical course of the disease is characterised by paroxysms of rapid coughs followed by inspiratory effort, often associated with a characteristic ‘whooping’ sound.
  • oxygen deprivation can lead to brain damage, however the most common complication is secondary pneumonia.
  • B. parapertussis is isolated from patients with typical signs and symptoms of whooping cough.
  • B. parapertussis infection is of lower frequency than B. pertussis with 5-10% of whooping cough being associated with B. parapertussis (Mertsola (1985) Eur J Clin Microbiol 4; 123; Lautrop (1971) Lancet 1(7711) 1195-1198).
  • B. parapertussis is associated with mild clinical symptoms which, combined with its serological cross-reactivity with B.pertussis , makes B. parapertussis difficult to diagnose.
  • the first generation of vaccines against B. pertussis were whole cell vaccines, composed of whole killed bacteria. These were introduced in many countries in the 1950s and 1960s and were successful at reducing the incidence of whooping cough.
  • a problem with whole cell B. pertussis vaccines is the high level of reactogenicity associated with them.
  • Acellular vaccines containing purified B. pertussis proteins are less reactogenic and have been adopted for the vaccination programmes of many countries.
  • PT pertussis toxin
  • FHA filamentous haemagglutinin
  • PRN pertactin
  • B. pertussis vaccines appears to protect against B. parapertussis infection, probably due to the similarity of the two bacteria.
  • B. parapertussis infection in unvaccinated infants may lead to severe and fatal complications, whereas in individuals vaccinated with Pw, a milder, often subclinical course of whooping cough is seen (Long et al (1990) Pediatric Infect Dis J 9; 700).
  • the introduction of acellular pertussis vaccines containing only two or three purified proteins could reduce the ability of vaccination to protect against B. parapertussis.
  • acellular vaccines against whooping cough are required that combine low reactogenicity with an ability to elicit a protective response against Bordetella , particularly both B. pertussis and B. parapertussis , infection.
  • Bordetella particularly both B. pertussis and B. parapertussis , infection.
  • the identification of new candidate antigens and particularly effective combinations of antigens will allow the development of such vaccines.
  • the present invention relates to immunogenic compositions containing BASB232, in particular BASB232 polypeptides or BASB232 polynucleotides, recombinant materials and methods for their production.
  • the invention relates to combination of polypeptides or nucleotides that interact advantageously in the prevention or treatment of microbial, particularly Bordetella , disease.
  • the invention relates to methods for using such polypeptides, polynucleotides and combinations, including prevention and treatment of Bordetella diseases, amongst others.
  • the invention relates to diagnostic assays for detecting diseases associated with microbial infections and conditions associated with such infections, such as assays for detecting expression or activity of BASB232 polynucleotides or polypeptides.

  • This aspect further defines previous embodiments of the invention and is also an independent embodiment of the invention.
  • a protein involved in Bordetella resistance to complement is defined as a Bordetella protein that is capable of disrupting the effective functioning of the host's complement system preferably by inhibiting the classical complement activation pathway.
  • the degree of inhibition will be at least 10%, preferably 20%, more preferably 30%, more preferably 40%, 50%, 60%, 70%, 80%, most preferably 90% or 95%. This may be measured by the ability of the protein to inhibit a serum killing assay as described in Infect. Immun. 69; 3067 (2001).
  • Examples of this sort of protein include BrkA and BrkB from Bordetella and fragments thereof eliciting an immunogenic response against said proteins, in particular a passenger domain (approximately from amino acid 41 to amino acid 706).
  • a protein involved in Bordetella resistance to cellular immunity is defined as a Bordetella protein which is able to inhibit (by at least 30%, 40%, 50%, 60%, 70%, 80%, preferably 90% or 95%) the effective functioning of at least one type of cell making up the host's cellular immunity system. It may act by having a toxic effect on one or more of the host's cell populations involved in cellular immunity, for instance T lymphocytes, B lymphocytes, neutrophils, eosinophils, macrophages, dendritic cells or monocytes. Examples of such antigens include pertussis toxin, adenylate cyclase and LPS. It may alternatively inhibit cellular immunity by disrupting the function of cell involved in immunity.
  • Bordetella pertussis is an obligate human pathogen and has developed mechanisms to survive within the hostile environment of the human host.
  • One mechanism of doing this is through the action of pertussis toxin, which catalyses the ADP-ribosylation of GTP-binding proteins of mammalian cells. Since GTP-binding proteins are signalling molecules involved in regulating cellular processes, such ADP-ribosylation can lead to disruption of cellular function.
  • GTP-binding proteins are signalling molecules involved in regulating cellular processes, such ADP-ribosylation can lead to disruption of cellular function.
  • Several important cells of the immune system including neutrophils, macrophages, monocytes and lymphocytes are inhibited by pertussis toxin (Weiss (1997) ASM News 63; 22). The action of pertussis toxin therefore disables the cellular immune response to B. pertussis.
  • the complement system is another important defence mechanism in the human body.
  • the level of complement in the lung is ordinarily 10-20% of that in serum, however this increases during inflammation (Persson (1991) Eur. Respir. 4; 1268).
  • B. pertussis has developed mechanisms of evading the complement system. Firstly, the lipopolysaccharides of B. pertussis do not activate the alternative pathway of complement (Fernandez and Weiss (1994) Infection and Immunity 62; 4727). The binding of antibodies to B. pertussis could however, lead to activation of the classical complement pathway. B. pertussis has developed a mechanism of inhibiting the classical complement pathway, using the protein BrkA.

  • compositions of the invention preferably comprise one or more additional cross-protective Bordetella antigen. It is advantageous for a vaccine to generate protection against B. parapertussis as well as B. pertussis so that a single vaccine can protect against both forms of infection. BrkA is itself well conserved between B. pertussis and B. parapertussis , however, a better level of protection is achieved by the inclusion of one or more additional antigens which are conserved between the several strains of Bordetella.
  • Bordetella cross-reactive antigens Several methods can be used to identify Bordetella cross-reactive antigens. Using genome mining, a comparison of the genomes of B. pertussis and B. parapertussis would show which antigens are conserved between the two species. Alternatively, DNA chips could be used alongside sequence information to assess the expression of candidate antigens in B. pertussis and B. parapertussis . Antisera against Pw could be used to identity cross-reactive antigens by using gel electrophoresis and western blotting. Spot microsequencing could precisely identify cross-reactive antigens. See Example 16 for one such suitable method.

Description

This application is a 371 of International Application No. PCT/EP2004/011082, filed 01 October 2004.
FIELD OF THE INVENTION
This invention relates to polynucleotides, (herein referred to as “BASB232 polynucleotide(s)”), polypeptides encoded by them (referred to herein as “BASB232” or “BASB232 polypeptide(s)”), recombinant materials and methods for their production. In particular, the invention relates to immunogenic compositions and vaccines containing single polypeptide or nucleotides or advantageous combinations thereof. In another aspect of the invention, the invention relates to methods for using such polypeptides and polynucleotides for the treatment or prevention of Bordetella infections. In a further aspect, the invention relates to diagnostic assays for detecting Bordetella infection
BACKGROUND OF THE INVENTION
The bacterium Bordetella pertussis is the causative agent for whooping cough, a respiratory disease that can be severe in infants and young children. The clinical course of the disease is characterised by paroxysms of rapid coughs followed by inspiratory effort, often associated with a characteristic ‘whooping’ sound. In serious cases, oxygen deprivation can lead to brain damage, however the most common complication is secondary pneumonia.
Whooping cough is usually considered to be caused by B. pertussis, but occasionally B. parapertussis is isolated from patients with typical signs and symptoms of whooping cough. B. parapertussis infection is of lower frequency than B. pertussis with 5-10% of whooping cough being associated with B. parapertussis (Mertsola (1985) Eur J Clin Microbiol 4; 123; Lautrop (1971) Lancet 1(7711) 1195-1198). B. parapertussis is associated with mild clinical symptoms which, combined with its serological cross-reactivity with B.pertussis, makes B. parapertussis difficult to diagnose.
The first generation of vaccines against B. pertussis were whole cell vaccines, composed of whole killed bacteria. These were introduced in many countries in the 1950s and 1960s and were successful at reducing the incidence of whooping cough. A problem with whole cell B. pertussis vaccines is the high level of reactogenicity associated with them. Acellular vaccines containing purified B. pertussis proteins are less reactogenic and have been adopted for the vaccination programmes of many countries. Acellular vaccines typically containing pertussis toxin (PT), filamentous haemagglutinin (FHA) and quite often pertactin (PRN), are widely used and provide effective protection from the severity of whooping cough.
Despite vaccination, whooping cough remains an endemic disease (Mooi et al (2001) Emerging Infectious Diseases 7; 526). Whooping cough has re-emerged in Australia, Canada and The Netherlands; countries with highly vaccinated populations. A comparison of pre-vaccination strains with strains isolated recently, has shown antigenic drift, particularly in PT and PRN (Mooi et al (1998) Infection and Immunity 66; 670). It is widely acknowledged that current vaccines protect against severe disease but do not eliminate Bordetella pertussis from the body (Cherry et al (1998) Vaccine 16; 1901, Hewlett and Halperin (1998) Vaccine 16; 1899, Storsaeter et al (1998) Vaccine 16; 1907). The defence mechanisms of Bordetella pertussis allow it to evade elimination from the body, indicating that current vaccines do not completely disable these defence mechanisms.
Vaccination using whole cell B. pertussis vaccines (Pw), appears to protect against B. parapertussis infection, probably due to the similarity of the two bacteria. B. parapertussis infection in unvaccinated infants may lead to severe and fatal complications, whereas in individuals vaccinated with Pw, a milder, often subclinical course of whooping cough is seen (Long et al (1990) Pediatric Infect Dis J 9; 700). Theoretically, the introduction of acellular pertussis vaccines containing only two or three purified proteins could reduce the ability of vaccination to protect against B. parapertussis.
Accordingly, further improved acellular vaccines against whooping cough are required that combine low reactogenicity with an ability to elicit a protective response against Bordetella, particularly both B. pertussis and B. parapertussis, infection. The identification of new candidate antigens and particularly effective combinations of antigens will allow the development of such vaccines.
SUMMARY OF THE INVENTION
The present invention relates to immunogenic compositions containing BASB232, in particular BASB232 polypeptides or BASB232 polynucleotides, recombinant materials and methods for their production. In a further aspect, the invention relates to combination of polypeptides or nucleotides that interact advantageously in the prevention or treatment of microbial, particularly Bordetella, disease. In another aspect, the invention relates to methods for using such polypeptides, polynucleotides and combinations, including prevention and treatment of Bordetella diseases, amongst others. In a further aspect, the invention relates to diagnostic assays for detecting diseases associated with microbial infections and conditions associated with such infections, such as assays for detecting expression or activity of BASB232 polynucleotides or polypeptides.
Various changes and modifications within the spirit and scope of the disclosed invention will become readily apparent to those skilled in the art from reading the following descriptions and from reading the other parts of the present disclosure.

Polypeptides
In one aspect of the invention there are provided polypeptides of B. pertussis referred to herein as “BASB232” and “BASB232 polypeptides” as well as biologically, diagnostically, prophylactically, clinically or therapeutically useful variants thereof and compositions, preferably immunogenic compositions comprising the same.
The present invention further provides for:
  • (a) an isolated polypeptide which comprises an amino acid sequence which has at least 85% identity, preferably at least 90% identity, more preferably at least 95% identity, most preferably at least 97, 98 or 99% or exact identity, to that of any sequence of SEQ Group 2;
  • (b) a polypeptide encoded by an isolated polynucleotide comprising a polynucleotide sequence which has at least 85% identity, preferably at least 90% identity, more preferably at least 95% identity, even more preferably at least 97, 98 or 99% or exact identity to any sequence of SEQ Group 1 over the entire length of the selected sequence of SEQ Group 1; or
  • (c) a polypeptide encoded by an isolated polynucleotide comprising a polynucleotide sequence encoding a polypeptide which has at least 85% identity, preferably at least 90% identity, more preferably at least 95% identity, even more preferably at least 97-99% or exact identity, to the amino acid sequence of any sequence of SEQ Group 2.
The BASB232 polypeptides provided in SEQ Group 2 are the BASB232 polypeptides from B. pertussis (or B. parapertussis) as described in table 1. It is envisaged that B. parapertussis (or B. pertussis) sequences may be used.
The invention also provides an immunogenic fragment of a BASB232 polypeptides, that is, a contiguous portion of the BASB232 polypeptide which has the same or substantially the same immunogenic activity as the polypeptide comprising the corresponding amino acid sequence selected from SEQ Group 2; That is to say, the fragment (if necessary when coupled to a carrier) is capable of raising an immune response which recognises the BASB232 polypeptide. Such an immunogenic fragment may include, for example, the BASB232 polypeptide lacking an N-terminal leader sequence, and/or a transmembrane domain and/or a C-terminal anchor domain. In a preferred aspect the immunogenic fragment of BASB232 according to the invention comprises substantially all of the extracellular domain of a polypeptide which has at least 85% identity, preferably at least 90% identity, more preferably at least 95% identity, most preferably at least 97-99% identity, to that a sequence selected from SEQ Group 2 over the entire length of said sequence.
A fragment is a polypeptide having an amino acid sequence that is entirely the same as part but not all of any amino acid sequence of any polypeptide of the invention. As with BASB232 polypeptides, fragments may be “free-standing,” or comprised within a larger polypeptide of which they form a part or region, most preferably as a single continuous region in a single larger polypeptide.
Preferred fragments include, for example, truncation polypeptides having a portion of an amino acid sequence selected from SEQ Group 2 or of variants thereof, such as a continuous series of residues that includes an amino- and/or carboxyl-terminal amino acid sequence. Degradation forms of the polypeptides of the invention produced by or in a host cell, are also preferred. Further preferred are fragments characterized by structural or functional attributes such as fragments that comprise alpha-helix and alpha-helix forming regions, beta-sheet and beta-sheet-forming regions, turn and turn-forming regions, coil and coil-forming regions, hydrophilic regions, hydrophobic regions, alpha amphipathic regions, beta amphipathic regions, flexible regions, surface-forming regions, substrate binding region, and high antigenic index regions.
Further preferred fragments include an isolated polypeptide comprising an amino acid sequence having at least 15, 20, 30, 40, 50 or 100 contiguous amino acids from the amino acid sequence selected from SEQ Group 2 or an isolated polypeptide comprising an amino acid sequence having at least 15, 20, 30, 40, 50 or 100 contiguous amino acids truncated or deleted from the amino acid sequence selected from SEQ Group 2.
The BASB232 polypeptides set out in SEQ ID 30, 32, 34, 36, 38, 40, 42, 44, 46, 48, 50, 52, 53 and 54 belong to an autotransporter proteins family. In this family, there are two domains: the passenger domain that is surface exposed and the beta domain that is anchored in the outer membrane protein. The passenger domain is a preferred fragment for vaccine use. The passenger domain was predicted for each of the BASB232 polypeptides set out in SEQ ID 30, 32, 34, 36, 38, 40, 42, 44, 50, 52 and 100 in table 2.

Fragments described in table 2 are preferred fragments. These fragments may be readily modified by adding or removing 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 20, 30, 40 or 50 amino acids from either or both of the N and C termini.
Still further preferred fragments are those which comprise a B-cell or T-helper epitope, for example those fragments/peptides described in Example 8.
Fragments of the polypeptides of the invention may be employed for producing the corresponding full-length polypeptide by peptide synthesis; therefore, these fragments may be employed as intermediates for producing the full-length polypeptides of the invention.
The term “fragment” encompasses the fragment itself or the fragment may be part of a larger protein or a fusion protein.
Particularly preferred are variants in which several, 5-10, 1-5, 1-3, 1-2 or 1 amino acids are substituted, deleted, or added in any combination.
The polypeptides, or immunogenic fragments, of the invention may be in the form of the “mature” protein or may be a part of a larger protein such as a precursor or a fusion protein. It is often advantageous to include an additional amino acid sequence which contains secretory or leader sequences, pro-sequences, sequences which aid in purification such as multiple histidine residues, or an additional sequence for stability during recombinant production. Furthermore, addition of exogenous polypeptide or lipid tail or polynucleotide sequences to increase the immunogenic potential of the final molecule is also considered.
In one aspect, the invention relates to genetically engineered soluble fusion proteins comprising a polypeptide of the present invention, or a fragment thereof, and various portions of the constant regions of heavy or light chains of immunoglobulins of various subclasses (IgG, IgM, IgA, IgE). Preferred as an immunoglobulin is the constant part of the heavy chain of human IgG, particularly IgG1, where fusion takes place at the hinge region. In a particular embodiment, the Fc part can be removed simply by incorporation of a cleavage sequence which can be cleaved with blood clotting factor Xa.
Furthermore, this invention relates to processes for the preparation of these fusion proteins by genetic engineering, and to the use thereof for drug screening, diagnosis and therapy. A further aspect of the invention also relates to polynucleotides encoding such fusion proteins. Examples of fusion protein technology can be found in International Patent Application Nos. WO94/29458 and WO94/22914.
The proteins may be chemically conjugated, or expressed as recombinant fusion proteins allowing increased levels to be produced in an expression system as compared to non-fused protein. The fusion partner may assist in providing T helper epitopes (immunological fusion partner), preferably T helper epitopes recognised by humans, or assist in expressing the protein (expression enhancer) at higher yields than the native recombinant protein. Preferably the fusion partner will be both an immunological fusion partner and expression enhancing partner.
Fusion partners include protein D from Haemophilus influenzae and the non-structural protein from influenza virus, NS1 (hemagglutinin). Another fusion partner is the protein known as Omp26 (WO 97/01638). Another fusion partner is the protein known as LytA. Preferably the C terminal portion of the molecule is used. LytA is derived from Streptococcus pneumoniae which synthesize an N-acetyl-L-alanine amidase, amidase LytA, (coded by the lytA gene {Gene, 43 (1986) page 265-272}) an autolysin that specifically degrades certain bonds in the peptidoglycan backbone. The C-terminal domain of the LytA protein is responsible for the affinity to the choline or to some choline analogues such as DEAE. This property has been exploited for the development of E.coli C-LytA expressing plasmids useful for expression of fusion proteins. Purification of hybrid proteins containing the C-LytA fragment at its amino terminus has been described {Biotechnology: 10, (1992) page 795-798}. It is possible to use the repeat portion of the LytA molecule found in the C terminal end starting at residue 178, for example residues 188-305.
The present invention also includes variants of the aforementioned polypeptides, that is polypeptides that vary from the referents by conservative amino acid substitutions, whereby a residue is substituted by another with like characteristics. Typical such substitutions are among Ala, Val, Leu and Ile; among Ser and Thr; among the acidic residues Asp and Glu; among Asn and Gln; and among the basic residues Lys and Arg; or aromatic residues Phe and Tyr.
Polypeptides of the present invention can be prepared in any suitable manner. Such polypeptides include isolated naturally occurring polypeptides, recombinantly produced polypeptides, synthetically produced polypeptides, or polypeptides produced by a combination of these methods. Means for preparing such polypeptides are well understood in the art.
It is most preferred that a polypeptide of the invention is derived from B. pertussis, however, it is optionally obtained from other organisms of the same taxonomic genus. A polypeptide of the invention may also be obtained, for example, from organisms of the same taxonomic family or order (for instance Bordetella parapertussis or Bordetella bronchosepaica).
Polynucleotides
It is an object of the invention to provide polynucleotides that encode BASB232 polypeptides, particularly polynucleotides that encode polypeptides herein designated BASB232.
In a particularly preferred embodiment of the invention the polynucleotide comprises a region encoding BASB232 polypeptides comprising sequences set out in SEQ Group 1 which include full length gene, or a variant or fragment thereof.
Polynucleotides of the invention do not encompass a complete genomic DNA from a Bordetella species, e.g. B. pertussis or B. parapertussis.
As a further aspect of the invention there are provided isolated nucleic acid molecules encoding and/or expressing BASB232 polypeptides and polynucleotides, particularly B. pertussis or B. parapertussis BASB232 polypeptides and polynucleotides, including, for example, unprocessed RNAs, ribozyme RNAs, mRNAs, cDNAs, B- and Z-DNAs. Further embodiments of the invention include biologically, diagnostically, prophylactically, clinically or therapeutically useful polynucleotides and polypeptides, and variants thereof, and compositions, preferably immunogenic compositions, comprising the same.
Another aspect of the invention relates to isolated polynucleotides, including at least one full length gene, that encode BASB232 polypeptides having a deduced amino acid sequence of SEQ Group 2 and polynucleotides closely related thereto and variants thereof.
In another particularly preferred embodiment of the invention relates to BASB232 polypeptides from B. pertussis or B. parapertussis comprising or consisting of an amino acid sequence selected from SEQ Group 2 or a variant thereof.
Using the information provided herein, such as a polynucleotide sequence set out in SEQ Group 1, a polynucleotide of the invention encoding BASB232 polypeptide may be obtained using standard cloning and screening methods, such as those for cloning and sequencing chromosomal DNA fragments from bacteria using B. pertussis strain Tohama I cells as starting material, followed by obtaining a full length clone. For example, to obtain a polynucleotide sequence of the invention, such as a polynucleotide sequence given in SEQ Group 1, typically a library of clones of chromosomal DNA of B. pertussis strain Tohama I in E. coli or some other suitable host is probed with a radiolabeled oligonucleotide, preferably a 17-mer or longer, derived from a partial sequence. Clones carrying DNA identical to that of the probe can then be distinguished using stringent hybridization conditions. By sequencing the individual clones thus identified by hybridization with sequencing primers designed from the original polypeptide or polynucleotide sequence it is then possible to extend the polynucleotide sequence in both directions to determine a full length gene sequence. Conveniently, such sequencing is performed, for example, using denatured double stranded DNA prepared from a plasmid clone. Suitable techniques are described by Maniatis, T., Fritsch, E. F. and Sambrook et al., MOLECULAR CLONING, A LABORATORY MANUAL, 2nd Ed.; Cold Spring Harbor Laboratory Press, Cold Spring Harbor, N.Y. (1989). (see in particular Screening By Hybridization 1.90 and Sequencing Denatured Double-Stranded DNA Templates 13.70). Direct genomic DNA sequencing may also be performed to obtain a full length gene sequence. Mustrative of the invention, each polynucleotide set out in SEQ Group 1 was discovered in a DNA library derived from B. pertussis or B. parapertussis.
Moreover, each DNA sequence set out in SEQ Group 1 contains an open reading frame encoding a protein having about the number of amino acid residues set forth in SEQ Group 2 with a deduced molecular weight that can be calculated using amino acid residue molecular weight values well known to those skilled in the art.
The polynucleotides of SEQ Group 1, between the start codon and the stop codon, encode respectively the polypeptides of SEQ Group 2. The nucleotide number of start codon and first nucleotide of the stop codon are listed in table 3 for each polynucleotide of SEQ Group 1.

In a further aspect, the present invention provides for an isolated polynucleotide comprising or consisting of:
  • (a) a polynucleotide sequence which has at least 85% identity, preferably at least 90% identity, more preferably at least 95% identity, even more preferably at least 97, 98 or 99% or exact identity to any sequence from SEQ Group 1 over the entire length of the polynucleotide sequence from SEQ Group 1; or
  • (b) a polynucleotide sequence encoding a polypeptide which has at least 85% identity, preferably at least 90% identity, more preferably at least 95% identity, even more preferably at least 97, 98 or 99% or 100% exact, to any amino acid sequence selected from SEQ Group 2, over the entire length of the amino acid sequence from SEQ Group 2.
A polynucleotide encoding a polypeptide of the present invention, including homologs and orthologs from species other than B. pertussis, may be obtained by a process which comprises the steps of screening an appropriate library under stringent hybridization conditions (for example, using a temperature in the range of 45-65° C. and an SDS concentration from 0.1-1%) with a labeled or detectable probe consisting of or comprising any sequence selected from SEQ Group 1 or a fragment thereof; and isolating a full-length gene and/or genomic clones containing said polynucleotide sequence.
The invention provides a polynucleotide sequence identical over its entire length to a coding sequence (open reading frame) set out in SEQ Group 1. Also provided by the invention is a coding sequence for a mature polypeptide or a fragment thereof, by itself as well as a coding sequence for a mature polypeptide or a fragment in reading frame with another coding sequence, such as a sequence encoding a leader or secretory sequence, a pre, or pro- or prepro-protein sequence. The polynucleotide of the invention may also contain at least one non-coding sequence, including for example, but not limited to at least one non-coding 5′ and 3′ sequence, such as the transcribed but non-translated sequences, termination signals (such as rho-dependent and rho-independent termination signals), ribosome binding sites, Kozak sequences, sequences that stabilize mRNA, introns, and polyadenylation signals. The polynucleotide sequence may also comprise additional coding sequence encoding additional amino acids. For example, a marker sequence that facilitates purification of the fused polypeptide can be encoded. In certain embodiments of the invention, the marker sequence is a hexa-histidine peptide, as provided in the pQE vector (Qiagen, Inc.) and described in Gentz et al, Proc. Natl. Acad Sci., USA 86. 821-824 (1989), or an HA peptide tag (Wilson et al, Cell 37: 767 (1984), both of which may be useful in purifying polypeptide sequence fused to them. Polynucleotides of the invention also include, but are not limited to, polynucleotides comprising a structural gene and its naturally associated sequences that control gene expression.
The nucleotide sequences encoding the BASB232 polypeptides of SEQ Group 2 may be identical to the corresponding polynucleotide encoding sequences of SEQ Group 1. The position of the first and last nucleotides of the encoding sequences of SEQ Group 1 are listed in table 4. Alternatively it may be any sequence, which as a result of the redundancy (degeneracy) of the genetic code, also encodes polypeptides of SEQ Group 2.

The term “polynucleotide encoding a polypeptide” as used herein encompasses polynucleotides that include a sequence encoding a polypeptide of the invention, particularly a bacterial polypeptide and more particularly a polypeptide of the B. pertussis or B parapertussis BASB232 having an amino acid sequence set out in any of the sequences of SEQ Group 2. The term also encompasses polynucleotides that include a single continuous region or discontinuous regions encoding the polypeptide (for example, polynucleotides interrupted by integrated phage, an integrated insertion sequence, an integrated vector sequence, an integrated transposon sequence, or due to RNA editing or genomic DNA reorganization) together with additional regions, that also may contain coding and/or non-coding sequences.
The invention further relates to variants of the polynucleotides described herein that encode variants of a polypeptides having a deduced amino acid sequence of any of the sequences of SEQ Group 2. Fragments of polynucleotides of the invention may be used, for example, to synthesize full-length polynucleotides of the invention.
Preferred fragments are those polynucleotides which encode a B-cell or T-helper epitope, for example the fragments/peptides described in Example 8, and recombinant, chimeric genes comprising said polynucleotide fragments.
Further particularly preferred embodiments are polynucleotides encoding BASB232 variants, that have the amino acid sequence of BASB232 polypeptides of any sequence from SEQ Group 2 in which several, a few, 5 to 10, 1 to 5, 1 to 3, 2, 1 or no amino acid residues are substituted, modified, deleted and/or added, in any combination. Especially preferred among these are silent substitutions, additions and deletions, that do not alter the properties and activities of BASB232 polypeptides.
Further preferred embodiments of the invention are polynucleotides that are at least 85% identical over their entire length to polynucleotides encoding BASB232 polypeptides having an amino acid sequence set out in any of the sequences of SEQ Group 2, and polynucleotides that are complementary to such polynucleotides. Alternatively, most highly preferred are polynucleotides that comprise a region that is at least 90% identical over its entire length to polynucleotides encoding BASB232 polypeptides and polynucleotides complementary thereto. In this regard, polynucleotides at least 95% identical over their entire length to the same are particularly preferred. Furthermore, those with at least 97% are highly preferred among those with at least 95%, and among these those with at least 98% and at least 99% are particularly highly preferred, with at least 99% being the more preferred.
Preferred embodiments are polynucleotides encoding polypeptides that retain substantially the same biological function or activity as mature polypeptides encoded by a DNA sequences selected from SEQ Group 1.
In accordance with certain preferred embodiments of this invention there are provided polynucleotides that hybridize, particularly under stringent conditions, to BASB232 polynucleotide sequences, such as those polynucleotides in SEQ Group 1.
The invention further relates to polynucleotides that hybridize to the polynucleotide sequences provided herein. In this regard, the invention especially relates to polynucleotides that hybridize under stringent conditions to the polynucleotides described herein. As herein used, the terms “stringent conditions” and “stringent hybridization conditions” mean hybridization occurring only if there is at least 95% and preferably at least 97% identity between the sequences. A specific example of stringent hybridization conditions is overnight incubation at 42° C. in a solution comprising: 50% formamide, 5×SSC (150 mM NaCl, 15 mM trisodium citrate), 50 mM sodium phosphate (pH7.6), 5× Denhardt's solution, 10% dextran sulfate, and 20 micrograms/ml of denatured, sheared salmon sperm DNA, followed by washing the hybridization support in 0.1×SSC at about 65° C.
Hybridization and wash conditions are well known and exemplified in Sambrook, et al., Molecular Cloning: A Laboratory Manual, Second Edition, Cold Spring Harbor, N.Y., (1989), particularly Chapter 11 therein. Solution hybridization may also be used with the polynucleotide sequences provided by the invention.
The invention also provides a polynucleotide consisting of or comprising a polynucleotide sequence obtained by screening an appropriate library containing the complete gene for a polynucleotide sequence set forth in any of the sequences of SEQ Group 1 under stringent hybridization conditions with a probe having the sequence of said polynucleotide sequence set forth in the corresponding sequences of SEQ Group 1 or a fragment thereof; and isolating said polynucleotide sequence. Fragments useful for obtaining such a polynucleotide include, for example, probes and primers fully described elsewhere herein.
As discussed elsewhere herein regarding polynucleotide assays of the invention, for instance, the polynucleotides of the invention, may be used as a hybridization probe for RNA, cDNA and genomic DNA to isolate fill-length cDNAs and genomic clones encoding BASB232 and to isolate cDNA and genomic clones of other genes that have a high identity, particularly high sequence identity, to the BASB232 genes. Such probes generally will comprise at least 15 nucleotide residues or base pairs. Preferably, such probes will have at least 30 nucleotide residues or base pairs and may have at least 50 nucleotide residues or base pairs. Particularly preferred probes will have at least 20 nucleotide residues or base pairs and will have less than 30 nucleotide residues or base pairs.
A coding region of BASB232 genes maybe isolated by screening using a DNA sequences provided in SEQ Group 1 to synthesize an oligonucleotide probe. A labeled oligonucleotide having a sequence complementary to that of a gene of the invention is then used to screen a library of cDNA, genomic DNA or mRNA to determine which members of the library the probe hybridizes to.
There are several methods available and well known to those skilled in the art to obtain full-length DNAs, or extend short DNAs, for example those based on the method of Rapid Amplification of cDNA ends (RACE) (see, for example, Frohman, et al., PNAS USA 85: 8998-9002, 1988). Recent modifications of the technique, exemplified by the Marathon™ technology (Clontech Laboratories Inc.) for example, have significantly simplified the search for longer cDNAs. In the Marathon™ technology, cDNAs have been prepared from mRNA extracted from a chosen tissue and an ‘adaptor’ sequence ligated onto each end. Nucleic acid amplification (PCR) is then carried out to amplify the “missing” 5′ end of the DNA using a combination of gene specific and adaptor specific oligonucleotide primers. The PCR reaction is then repeated using “nested” primers, that is, primers designed to anneal within the amplified product (typically an adaptor specific primer that anneals further 3′ in the adaptor sequence and a gene specific primer that anneals further 5′ in the selected gene sequence). The products of this reaction can then be analyzed by DNA sequencing and a full-length DNA constructed either by joining the product directly to the existing DNA to give a complete sequence, or carrying out a separate full-length PCR using the new sequence information for the design of the 5′ primer.
The polynucleotides and polypeptides of the invention may be employed, for example, as research reagents and materials for discovery of treatments of and diagnostics for diseases, particularly human diseases, as further discussed herein relating to polynucleotide assays.
The polynucleotides of the invention that are oligonucleotides derived from a sequence of SEQ Group 1 may be used in the processes herein as described, but preferably for PCR, to determine whether or not the polynucleotides identified herein in whole or in part are transcribed in bacteria in infected tissue. It is recognized that such sequences will also have utility in diagnosis of the stage of infection and type of infection the pathogen has attained.
The invention also provides polynucleotides that encode a polypeptide that is the mature protein plus additional amino or carboxyl-terminal amino acids, or amino acids interior to the mature polypeptide (when the mature form has more than one polypeptide chain, for instance). Such sequences may play a role in processing of a protein from precursor to a mature form, may allow protein transport, may lengthen or shorten protein half-life or may facilitate manipulation of a protein for assay or production, among other things. As generally is the case in vivo, the additional amino acids may be processed away from the mature protein by cellular enzymes.
For each and every polynucleotide of the invention there is provided a polynucleotide complementary to it. It is preferred that these complementary polynucleotides are fully complementary to each polynucleotide with which they are complementary.
A precursor protein, having a mature form of the polypeptide fused to one or more prosequences may be an inactive form of the polypeptide. When prosequences are removed such inactive precursors generally are activated. Some or all of the prosequences may be removed before activation. Generally, such precursors are called proproteins.
In addition to the standard A, G, C, T/U representations for nucleotides, the term “N” may also be used in describing certain polynucleotides of the invention. “N” means that any of the four DNA or RNA nucleotides may appear at such a designated position in the DNA or RNA sequence, except it is preferred that N is not a nucleic acid that when taken in combination with adjacent nucleotide positions, when read in the correct reading frame, would have the effect of generating a premature termination codon in such reading frame.
In sum, a polynucleotide of the invention may encode a mature protein, a mature protein plus a leader sequence (which may be referred to as a preprotein), a precursor of a mature protein having one or more prosequences that are not the leader sequences of a preprotein, or a preproprotein, which is a precursor to a proprotein, having a leader sequence and one or more prosequences, which generally are removed during processing steps that produce active and mature forms of the polypeptide.
In accordance with an aspect of the invention, there is provided the use of a polynucleotide of the invention for therapeutic or prophylactic purposes, in particular genetic immunization.
The use of a polynucleotide of the invention in genetic immunization will preferably employ a suitable delivery method such as direct injection of plasmid DNA into muscles (Wolff et al., Hum Mol Genet (1992) 1: 363, Manthorpe et al., Hum. Gene Ther. (1983) 4: 419), delivery of DNA complexed with specific protein carriers (Wu et al., J Biol Chem. (1989) 264: 16985), coprecipitation of DNA with calcium phosphate (Benvenisty & Reshef, PNAS USA, (1986) 83: 9551), encapsulation of DNA in various forms of liposomes (Kaneda et al., Science (1989) 243: 375), particle bombardment (Tang et al., Nature (1992) 356:152, Bisenbraun et al., DNA Cell Biol (1993) 12: 791) and in vivo infection using cloned retroviral vectors (Seeger et al., PNAS USA (1984) 81: 5849).
Vectors, Host Cells, Expression Systems
The invention also relates to vectors that comprise a polynucleotide or polynucleotides of the invention, host cells that are genetically engineered with vectors of the invention and the production of polypeptides of the invention by recombinant techniques. Cell-free translation systems can also be employed to produce such proteins using RNAs derived from the DNA constructs of the invention.
Recombinant polypeptides of the present invention may be prepared by processes well known in those skilled in the art from genetically engineered host cells comprising expression systems. Accordingly, in a further aspect, the present invention relates to expression systems that comprise a polynucleotide or polynucleotides of the present invention, to host cells which are genetically engineered with such expression systems, and to the production of polypeptides of the invention by recombinant techniques.
For recombinant production of the polypeptides of the invention, host cells can be genetically engineered to incorporate expression systems or portions thereof or polynucleotides of the invention. Introduction of a polynucleotide into the host cell can be effected by methods described in many standard laboratory manuals, such as Davis, et al., BASIC METHODS IN MOLECULAR BIOLOGY, (1986) and Sambrook, et al., MOLECULAR CLONING: A LABORATORY MANUAL, 2nd Ed., Cold Spring Harbor Laboratory Press, Cold Spring Harbor, N.Y. (1989), such as, calcium phosphate transfection, DEAE-dextran mediated transfection, transvection, microinjection, cationic lipid-mediated transfection, electroporation, conjugation, transduction, scrape loading, ballistic introduction and infection.
Representative examples of appropriate hosts include bacterial cells, such as cells of streptococci, staphylococci, enterococci, E. coli, streptomyces, cyanobacteria, Bacillus subtilis, Neisseria meningitidis, Haemophilus influenzae and Moraxella catarrhalis; fungal cells, such as cells of a yeast, Kluveromyces, Saccharomyces, Pichia, a basidiomycete, Candida albicans and Aspergillus; insect cells such as cells of Drosophila S2 and Spodoptera Sf9; animal cells such as CHO, COS, HeLa, C127, 3T3, BHK, 293, CV-1 and Bowes melanoma cells; and plant cells, such as cells of a gymnosperm or angiosperm.
A great variety of expression systems can be used to produce the polypeptides of the invention. Such vectors include, among others, chromosomal-, episomal- and virus-derived vectors, for example, vectors derived from bacterial plasmids, from bacteriophage, from transposons, from yeast episomes, from insertion elements, from yeast chromosomal elements, from viruses such as baculovinises, papova viruses, such as SV40, vaccinia viruses, adenoviruses, fowl pox viruses, pseudorabies viruses, picornaviruses, retroviruses, and alphaviruses and vectors derived from combinations thereof, such as those derived from plasmid and bacteriophage genetic elements, such as cosmids and phagemids. The expression system constructs may contain control regions that regulate as well as engender expression. Generally, any system or vector suitable to maintain, propagate or express polynucleotides and/or to express a polypeptide in a host may be used for expression in this regard The appropriate DNA sequence may be inserted into the expression system by any of a variety of well-known and routine techniques, such as, for example, those set forth in Sambrook et al., MOLECULAR CLONING, A LABORATORY MANUAL, (supra).
In recombinant expression systems in eukaryotes, for secretion of a translated protein into the lumen of the endoplasmic reticulum, into the periplasmic space or into the extracellular environment, appropriate secretion signals may be incorporated into the expressed polypeptide. These signals may be endogenous to the polypeptide or they may be heterologous signals.
Polypeptides of the present invention can be recovered and purified from recombinant cell cultures by well-known methods including ammonium sulfate or ethanol precipitation, acid extraction, anion or cation exchange chromatography, phosphocellulose chromatography, hydrophobic interaction chromatography, affinity chromatography, hydroxylapatite chromatography and lectin chromatography. Most preferably, ion metal affinity chromatography (IMAC) is employed for purification. Well known techniques for refolding proteins may be employed to regenerate active conformation when the polypeptide is denatured during intracellular synthesis, isolation and or purification.
The expression system may also be a recombinant live microorganism, such as a virus or bacterium The gene of interest can be inserted into the genome of a live recombinant virus or bacterium. Inoculation and in vivo infection with this live vector will lead to in vivo expression of the antigen and induction of immune responses. Viruses and bacteria used for this purpose are for instance: poxviruses (e.g; vaccinia, fowlpox, canarypox), alphaviruses (Sindbis virus, Semliki Forest Virus, Venezuelian Equine Encephalitis Virus), adenoviruses, adeno-associated virus, picomaviruses (poliovirus, rhinovirus), herpesviruses (varicella zoster virus, etc), Listeria, Salmonella , Shigella, BCG, streptococci. These viruses and bacteria can be virulent, or attenuated in various ways in order to obtain live vaccines. Such live vaccines also form part of the invention.
Combinations of Bordetella Antigens in Immunogenic Compositions
A further aspect of the invention discloses particular combinations of Bordetella antigens which when combined, lead to an effective immunogenic composition against Bordetella infection. The efficacy of the immunogenic composition is determined as by its ability to elicit a protective response against B. pertussis primarily, but it is preferred that they also elicit a protective effect against the related bacteria B. parapertussis and/or B. bronchiseptica.
Preferred combinations of Bordetella antigens, when combined in an immunogenic composition or vaccine, allow different Bordetella functions to be targetted by the immune response. Such an immune response is better able to treat or prevent Bordetella infection. For instance, known virulence factors include adhesins like FHA, fimbrae, pertactin which are involved in attachment of Bordetella to host cells; toxins such as pertussis toxin, adenylate cyclase have a role in disabling the host immune system; BrkA acts as a serum resistance factor and TcfA has a role in tracheal colonization.
In particular, combinations of certain antigens from different classes, some of which are involved in adhesion to host cells, some of which are involved in iron acquisition, some of which are antotransporters and some of which are toxins, can elicit an immune response which protects against multiple functions of Bordetella required to sustain infection. Such combinations of antigens can surprisingly lead to improved vaccine efficacy against Bordetella infection where more that one function of the bacterium is targeted by the immune response. Preferably, the improved vaccine efficacy is against B. pertussis and/or B. parapertussis.
Accordingly, the invention provides immunogenic compositions comprising at least or exactly two, three, preferably four, five, six, seven, eight, nine or ten different Bordetella, preferably B. pertussis antigens, wherein the antigens are selected from at least two, three, four or five of the following categories:
    • a) at least one Bordetella autotransporter protein selected from the group consisting of a polypeptide sharing at least 70%, 80%; 90%, 95%, 97%, 98%, 99% or 100% identity with SEQ ID 34, 30, 32, 36, 38, 40, 42, 44, 46, 48, 50, 52, 54 or 100, pertactin and BipA, or an antigenic or immunogenic fragment thereof, preferably a passenger domain thereof;
    • b) at least one Bordetella iron acquisition protein selected from the group consisting of the polypeptide sharing at least 70%, 80%, 90%, 95%, 97%, 98%, 99% or 100% identity with SEQ ID 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28 or 106, or an antigenic or immunogenic fragment thereof;
    • c) at least one Bordetella lipoprotein selected from the group consisting of the polypeptide sharing at least 70%, 80%, 90%, 95%, 97%, 98%, 99% or 100% identity with SEQ ID 56, 58, 60, 62, 64, 66, 68, 70, 72, 74, 76, 78, 80, 82, 84, 86, 88, 90, 92, 94, 96, or 98 or an antigenic or immunogenic fragment thereof;
    • d) at least one Bordetella adhesin selected from the group consisting of FHA, fimbriae, pertactin and BrkA or an antigenic or immunogenic fragment thereof; and
    • e) at least one Bordetella toxin/invasin or antigens involved in toxin/invasin secretion selected from the group consisting of pertussis toxin, adenylate cyclase, dermonecrotic toxin (Dnt), Type IIIss or lipopolysaccharide or an antigenic or immunogenic fragment thereof,
      wherein the Bordetella antigens in the immunogenic composition do not consist of any combination of 2, 3, 4 or all 5 of pertactin, fimbriae 2, fimbrae 3, FHA and pertussis toxin.
The combinations of the invention do not include whole cell pertussis (Pw).
Immunogenic compositions of the invention therefore do not cover known vaccine combinations (for instance vaccines where the acellular pertussis component consist of 2, 3, 4 or 5 of FHA, pertussis toxoid, pertactin, fimbrae 2 and fimbrae 3) however a single known antigen from one group, combined with a new antigen from a different group is covered.
The Bordetella antigens may derived from any strain of Bordetella including from one or more of B. pertussis, B. parapertussis and B. bronchiseptica (preferably the former).
Preferably all five groups of antigen are represented in the immunogenic composition of the invention. Where an antigen falls into two groups, the inclusion of that one antigen into an immunogenic composition leads to the inclusion of both groups in the immunogenic composition.
Where a protein is specifically mentioned herein, it is preferably a reference to a native, full-length protein but it may also encompass antigenic, preferably immunogenic fragments thereof (particularly in the context of subunit vaccines). These are fragments containing or comprising at least 10 amino acids, preferably at least 20 amino acids, more preferably at least 30 amino acids, more preferably at least 40 amino acids or most preferably at least 50 amino acids, taken contiguously from the amino acid sequence of the protein wherein the fragment is shorter than the full length of the protein. Particularly preferred fragments are the passenger domains of autotransporter proteins as defined above. In addition, antigenic fragments denotes fragments that are immunologically reactive with antibodies generated against the B. pertussis proteins or with antibodies generated by infection of a mammalian host with Bordetella. Antigenic fragments also includes fragments that when administered at an effective dose, elicit a protective immune response against Bordetella infection, more preferably it is protective against B. pertussis and/or B. parapertussis and/or B. bronchiseptica infection. Preferably such fragments are coupled to a source of T—cell epitopes.
Also included in the invention are recombinant fusion proteins of Bordetella proteins of the invention, or fragments thereof. These may combine different Bordetella proteins or fragments thereof in the same polypeptide. Alternatively, the invention also includes individual fusion proteins of Bordetella proteins or fragments thereof, as a fusion protein with heterologous sequences such as a provider of T-ell epitopes or purification tags, for example: β-galactosidase, glutathione-S-transferase, green fluorescent proteins (GFP), epitope tags such as FLAG, myc tag, poly histidine, or viral surface proteins such as influenza virus haemagglutinin, tetanus toxoid, diphtheria toxoid, CRM197.
Antigens of the Invention
1. Autotransporter Proteins
Autotransporter proteins typically are made up of a signal sequence, a passenger domain and an anchoring domain for attachment to the outer membrane. Examples of autotransporter proteins include pertactin (SEQ ID 30), Vag8 (SEQ ID 32), BrkA (SEQ ID 34), TcfA (SEQ ID 36) (Finn and Stevens (1995) Mol. Microbiol. 16; 625-634), Phg (SEQ ID 38), BipA (Stockbauer et al 2001; Molecular Microbiology 39; 65-78), BapA (SEQ ID 40), BapB (SEQ ID 42), BapC (SEQ ID 44), pertactin-like protein (SEQ ID 46), Tcf-like protein (SEQ ID 48), extracellular serine protease (SEQ ID 50, SEQ ID 100), YapE (SEQ ID 52), SphBI (SEQ ID 54). These antigens may be derived from Bordetella pertussis or Bordetella parapertussis or other Bordetella strains.
It is particularly advantageous to use the passenger domain of an autotranporter when it is included in a subunit vaccine. Table 2 above defines the passsenger domains of the autotransporter proteins listed above.
BipA contains 90 amino acid tandem repeats with 5 being present in the B. pertussis protein and 8 being present in the B. bronchiseptica protein. These repeats span from amino acid 581 to 1030 in B. pertussis and amino acids 581 to 1300 in B. bronchiseptica. Preferred fragments of BipA include amino acids 1031 to 1308, amino acids 941 to 1308, amino acids 851 to 1308, amino acids 761 to 1308, amino acids 671 to 1308 and 581 to 1308 of the B. pertusis sequence (or sequences related to these that have 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 20, 30, 40 or 50 amino acids added or deleted from either or both of the N and C termini).
2. Iron Acquisition Proteins
Iron acquisition is of great importance to mammalian pathogens as iron is present in limiting conditions in the host and any iron that is present is sequestered by haem and other iron-chelating compounds. Iron from siderophores and host iron-binding complexes is internalised through TonB-dependent outer membrane ferric complex receptors. Bordetella iron aquisition proteins include BfeA (SEQ ID 2), BfrB (SEQ ID 4), BfrC (SEQ ID 6), FauA (SEQ ID 8), ferric siderophore receptor (SEQ ID 10), Ferric alcaligin siderophore receptor (SEQ ID 12), iron tranport protein fiu (SEQ ID 14, SEQ ID 106), iron tranport protein flu (SEQ ID 16), putative hydrxamate-type ferrisiderophore receptor signal peptide protein (SEQ ID 18) BhuR (SEQ ID 20) (Infection and Immunity 2001, 69; 6951), tonb-dependent receptor (SEQ ID 22), tonb-dependent receptor (SEQ ID 24), ferrisiderophore receptor-like protein (SEQ ID 26) and tonb-dependent receptor Yncd precurser (SEQ ID 28). These proteins may be derived from Bordetella pertussiss, Bordetella parapertussis or other Bordetella strains, preferably the former.
3. Lipoproteins
Bordetella lipoproteins include heme/hemopexin utilisation protein C presursor (SEQ ID 56), piln protein (SEQ ID 58), immunogenic protein (SEQ ID 60), outer membrane lipoprotein precursor (SEQ ID 62), outer membrane efflux protein precursor (SEQ ID 64), Oprm (SEQ ID 66), outer membrane channel signal protein (SEQ ID 68), MltA (SEQ ID 70), MTB (SEQ ID 72), yccz precursor (SEQ ID 74), serine protease transmembrane protein (SEQ ID 76), pa4632 (SEQ ID 78), coml precursor (SEQ ID 80), VacJ (SEQ ID 82), outer membrane lipoportein (SEQ ID 84), Flagelar 1-ring protein (SEQ ID 86), Ydcl (SEQ ID 88), Pal (SEQ ID 90), OmlA (SEQ ID 92), Smc00354 (SEQ ID 94), Pcp (SEQ ID 96) and lipoprotein (SEQ ID 98).
The lipoproteins having the sequence of SEQ ID 56-96 contain a lipidation motif indicating that they would be lipidated and inserted into the membrane. In its simplest form, the lipidation motif contains the concensus sequence LXXC. However, the concensus sequence is preferably close to the amino terminus of the sequence, within the larger concensus sequence:

<indicates the amino terminus of the protein so that the first amino acid should be M, V or L. {1, 40} indicates that between 1 and 40 amino acids should be present between the first amino acid and the rest of the concensus sequence. (D, E, R, K, *)6 indicates that the next 6 amino acids should not be D, E, R or K. The following 2 amino acids should be one of the aliphatic amino acids indicated and is preferably L. For the following 2 amino acids, the amino acids shown in the parentheses should be present and the final amino acid of the sequence shold be C. These antigens may be derived from Bordetella pertussis or Bordetella parapertussis, Bordetella bronchoseptica or other Bordetella strains, preferably the former.
4. Adhesins
Adhesins have a role in attaching Bordetella to a host cell and hence have important roles in virulence. They include filamentous haemagglutinin (FHA) (Relman et al (1989) Proc Natl Acad Sci USA 86; 2634-2641), fimbriae (Fim) (Mooi et al (1992) Microb Pathog 12; 127-135), pertactin (Roberts et al (1991) Mol Microbiol 5; 1393-1404) and BrkA (Fernandez et al (1994) Infection and Immunity 62; 4727-4738). These antigens may be derived from Bordetella pertussis or Bordetella parapertussis, Bordetella bronchoseptica or other Bordetella strains, preferably the former.
Fimbriae or Fim proteins are also known as aggutinins or fimbrial adhesins. The term Fim comprises fimbriae 2 and fimbriae 3.
5. Toxins
Toxins include adenylate cyclase (CyaA) (Hewlett et al (1989) J. Biol. Chem. 264; 19379-19384), pertussis toxin (Munoz et al (1981) Infect Immun 33; 820-826), dermo-necrotic toxin (Dnt) (Livey (1984) J. Med. Microbiol. 17; 91-103 and lipopolysaccharides. Toxins also include proteins that are involved in the secretion of toxins since an immune response against the secretory mechanism would prevent the efficient functioning of the secretory mechanism and lead to reduced toxin secretion. An example of such an antigen is the Type III secretion system (Yuk et al (2000) Mol. Microbiol. 35; 991-1004). These antigens may be derived from Bordetella pertussis or Bordetella parapertussis, Bordetella bronchoseptica or other Bordetella strains, preferably the former.
Preferred fragments of adenylate cyclase comprise amino acids 385-399 or sequences related to this that have 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 20, 30, 40 or 50 amino acids added to either or both of the N and C termini. Preferred fragments are disclosed in EP424518, EP787796 or WO 90/13312.
Where toxin is described herein, non-toxic derivatives such as toxoids or mutant toxins are also envisaged to be covered by the term.

It is further advantageous to combine antigens that are present at different stages of Bordetella life cycle in the immunogenic compositions of the invention. Bordetella has three identifyable stages, during which protein expression is controlled by the bvgAS locus. The Bvg+ virulent phase is characterised by the expression of a number of virulence factors including FHA, fimbrae and pertactin, a variety of toxins including adenylate cyclase, dermonecrotic toxin and pertussis toxin. During the Bvgi phase, some of the virulence factors are expressed and a new set of proteins including BipA are expressed (Deora et al Moledular Microbiology (2001) 40; 669-683).
immunogenic compositions comprising antigens expressed in different stages of the Bordetella life cycle further defines previous embodiments of the invention and is also an independent embodiment of the invention.
Antigens expressed in the Bvg phases can be determined as set out in Deora et al Molecular Microbiology (2001) 40; 669-683; Stockbauer et al Molecular Microbiology (2001) 39; 65-78; Cotter and Miller (1994) Infect. Immun. 62; 3381-3390 and Scarlato and Rappuoli (1991) J. Bacteriol. 173; 7401-7404 and U.S. Pat. No. 6,387,377.
Currently available acellular pertussis vaccines include FHA, adenylate cyclase, pertactin and fimbrae proteins which are all Bvg+ early genes. Accordingly, a further aspect of the invention is an immunogenic composition containing 2, 3, 4, 5, 6, 7, 8, 9, or 10 or more antigens which are expressed in two, three or four phases selected from Bvg+ early, Bvg+ late, Bvg− and Bvgi, for example, Bvg+ early and Bvg+ late; Bvg+ early and Bvg−; Bvg+ early and Bvgi: Bvg+ late and Bvg−; Bvg+ late and Bvgi; Bvg− and Bvgi; Bvg+ early and Bvg+ late and Bvg−; Bvg+ early and Bvg+ late and Bvgi; Bvg+ early and Bvg− and Bvgi; Bvg+ late and Bvg− and Bvgi; Bvg+early and Bvg+ late and Bvg− and Bvgi.
FHA, pertussis toxin, adenylate cyclase, Fim and pertactin are expressed in Bvg+ early phase.

Accordingly, preferred immunogenic compositions of the invention comprise 1, 2 or 3 antigens expressed in Bvg+ early phase (preferably selected from FHA, pertussis toxin, Fim and pertactin and further comprise 1, 2 or 3 antigens that are expressed during Bvg+ late phase and/or Bvgi phase and/or Bvg− phase (preferably Bvgi).

The combinations listed above may be in the form of a subunit vaccine which contains isolated, preferably purified antigens. Where this is the case, it is preferred that soluble fragments of some of the antigens are used. For instance, the water soluble passenger domain of autotransporter proteins as defined above are preferred.
A further aspect of the invention is a combination of a protein involved in Bordetella resistance to complement (for example BrkA) and an antigen involved in Bordetella resistance to cellular immunity (for instance pertssis toxin). Such a combination preferably elicits a protective immune response against Bordetella. This aspect further defines previous embodiments of the invention and is also an independent embodiment of the invention.
A protein involved in Bordetella resistance to complement is defined as a Bordetella protein that is capable of disrupting the effective functioning of the host's complement system preferably by inhibiting the classical complement activation pathway. The degree of inhibition will be at least 10%, preferably 20%, more preferably 30%, more preferably 40%, 50%, 60%, 70%, 80%, most preferably 90% or 95%. This may be measured by the ability of the protein to inhibit a serum killing assay as described in Infect. Immun. 69; 3067 (2001). Examples of this sort of protein include BrkA and BrkB from Bordetella and fragments thereof eliciting an immunogenic response against said proteins, in particular a passenger domain (approximately from amino acid 41 to amino acid 706).
A protein involved in Bordetella resistance to cellular immunity is defined as a Bordetella protein which is able to inhibit (by at least 30%, 40%, 50%, 60%, 70%, 80%, preferably 90% or 95%) the effective functioning of at least one type of cell making up the host's cellular immunity system. It may act by having a toxic effect on one or more of the host's cell populations involved in cellular immunity, for instance T lymphocytes, B lymphocytes, neutrophils, eosinophils, macrophages, dendritic cells or monocytes. Examples of such antigens include pertussis toxin, adenylate cyclase and LPS. It may alternatively inhibit cellular immunity by disrupting the function of cell involved in immunity.
Bordetella pertussis is an obligate human pathogen and has developed mechanisms to survive within the hostile environment of the human host. One mechanism of doing this is through the action of pertussis toxin, which catalyses the ADP-ribosylation of GTP-binding proteins of mammalian cells. Since GTP-binding proteins are signalling molecules involved in regulating cellular processes, such ADP-ribosylation can lead to disruption of cellular function. Several important cells of the immune system including neutrophils, macrophages, monocytes and lymphocytes are inhibited by pertussis toxin (Weiss (1997) ASM News 63; 22). The action of pertussis toxin therefore disables the cellular immune response to B. pertussis.
The complement system is another important defence mechanism in the human body. The level of complement in the lung is ordinarily 10-20% of that in serum, however this increases during inflammation (Persson (1991) Eur. Respir. 4; 1268). B. pertussis has developed mechanisms of evading the complement system. Firstly, the lipopolysaccharides of B. pertussis do not activate the alternative pathway of complement (Fernandez and Weiss (1994) Infection and Immunity 62; 4727). The binding of antibodies to B. pertussis could however, lead to activation of the classical complement pathway. B. pertussis has developed a mechanism of inhibiting the classical complement pathway, using the protein BrkA.
An aspect of the invention relates to a pharmaceutical composition, preferably an immunogenic composition, more preferably a vaccine and more preferably an acellular vaccine against Bordetella infection, comprising an antigen involved in Bordetella resistance to complement and an antigen involved in Bordetella resistance to cellular immunity. Such antigens may be proteins, lipoproteins, polysaccharides, lipopolysaccharides or any other constituent of Bordetella.
In a preferred embodiment of the invention, the pharmaceutical composition comprises BrkA and/or BrkB as a protein involved in Bordetella resistance to complement and PT and/or adenylate cyclase as a protein involved in Bordetella resistance to cellular immunity. Lipopolysaccharides (LPS) are antigens that are also toxic to cells involved in immunity and in some embodiments of the invention could supplement or replace pertussis toxin or adenylate cyclase. In a further embodiment of the invention, the pharmaceutical composition comprises BrkA as a protein involved in Bordetella resistance to complement, PT as a protein involved in Bordetella resistance to cellular immunity and FHA. In a further embodiment of the invention, the pharmaceutical composition comprises BrkA as a protein involved in Bordetella resistance to complement, PT as a protein involved in Bordetella resistance to cellular immunity, FHA and 69 kDa pertactin.
The pharmaceutical compositions of the invention preferably comprise one or more additional cross-protective Bordetella antigen. It is advantageous for a vaccine to generate protection against B. parapertussis as well as B. pertussis so that a single vaccine can protect against both forms of infection. BrkA is itself well conserved between B. pertussis and B. parapertussis, however, a better level of protection is achieved by the inclusion of one or more additional antigens which are conserved between the several strains of Bordetella.
Several methods can be used to identify Bordetella cross-reactive antigens. Using genome mining, a comparison of the genomes of B. pertussis and B. parapertussis would show which antigens are conserved between the two species. Alternatively, DNA chips could be used alongside sequence information to assess the expression of candidate antigens in B. pertussis and B. parapertussis. Antisera against Pw could be used to identity cross-reactive antigens by using gel electrophoresis and western blotting. Spot microsequencing could precisely identify cross-reactive antigens. See Example 16 for one such suitable method. The invention embodies vaccines containing cross-reactive Bordetella antigens identified by the above methods or similar methods (preferably proteins from SEQ Group 2, most preferably proteins having an amino acid sequence having at least 80%, 85%, 90%, 95%, 96%, 97%, 98% or 99% or 100% identity to SEQ ID NO: 14, 50, 100. 102, 104, 106, 108 or 110).
Preferred ratios of antigens for inclusion into a pharmaceutical composition are 1-10 PT to 1 BrkA or BrkB, more preferred ratios are 1-5 PT to 1 BrkA or BrkB, most preferred ratio are 2.5 PT to 1 BrkA or BrkB.
The incorporation of B. pertussis/B. parapertussis crossprotective antigens into the immunogenic compositions of the invention further defines previously described embodiments of the invention and is also an independent embodiment of the invention, namely an immunogenic composition (or acellular vaccine) comprising one or more antigens (preferably isolated from either or both of B. pertussis or B. parapertussis, particularly those antigens described in Example 16) that is capable of generating an immune response that is crossreactive against B. pertussis and B. parapertussis, preferably crossprotective against Bordetella disease, more preferably against B. pertussis and B. parapertussis disease, with the proviso that the immunogenic composition does not comprise whole cell pertussis (Pw).
Diagnostic, Prognostic, Serotyping and Mutation Assays
This invention is also related to the use of BASB232 polynucleotides and polypeptides of the invention for use as diagnostic reagents. Detection of BASB232 polynucleotides and/or polypeptides in a eukaryote, particularly a mammal, and especially a human, will provide a diagnostic method for diagnosis of disease, staging of disease or response of an infectious organism to drugs. Eukaryotes, particularly mammals, and especially humans, particularly those infected or suspected to be infected with an organism comprising a BASB232 genes or proteins, may be detected at the nucleic acid or amino acid level by a variety of well known techniques as well as by methods provided herein.
Polypeptides and polynucleotides for prognosis, diagnosis or other analysis may be obtained from a putatively infected and/or infected individual's bodily materials. Polynucleotides from any of these sources, particularly DNA or RNA, may be used directly for detection or may be amplified enzymatically by using PCR or any other amplification technique prior to analysis. RNA, particularly mRNA, cDNA and genomic DNA may also be used in the same ways. Using amplification, characterization of the species and strain of infectious or resident organism present in an individual, may be made by an analysis of the genotype of a selected polynucleotide of the organism. Deletions and insertions can be detected by a change in size of the amplified product in comparison to a genotype of a reference sequence selected from a related organism, preferably a different species of the same genus or a different strain of the same species. Point mutations can be identified by hybridizing amplified DNA to labeled BASB232 polynucleotide sequences. Perfectly or significantly matched sequences can be distinguished from imperfectly or more significantly mismatched duplexes by DNase or RNase digestion, for DNA or RNA respectively, or by detecting differences in melting temperatures or renaturation kinetics. Polynucleotide sequence differences may also be detected by alterations in the electrophoretic mobility of polynucleotide fragments in gels as compared to a reference sequence. This may be carried out with or without denaturing agents. Polynucleotide differences may also be detected by direct DNA or RNA sequencing. See, for example, Myers et al., Science, 230: 1242 (1985). Sequence changes at specific locations also may be revealed by nuclease protection assays, such as RNase, V1 and S1 protection assay or a chemical cleavage method. See, for example, Cotton et al., Proc. Natl. Acad. Sci., USA, 85: 4397-4401 (1985).
In another embodiment, an array of oligonucleotides probes comprising BASB232 nucleotide sequences or fragments thereof can be constructed to conduct efficient screening of, for example, genetic mutations, serotype, taxonomic classification or identification. Array technology methods are well known and have general applicability and can be used to address a variety of questions in molecular genetics including gene expression, genetic linkage, and genetic variability (see, for example, Chee et al., Science, 274: 610 (1996)).
Thus in another aspect, the present invention relates to a diagnostic kit which comprises:
  • (a) a polynucleotide of the present invention, preferably any of the nucleotide sequences of SEQ Group 1, or a fragment thereof;
  • (b) a nucleotide sequence complementary to that of (a);
  • (c) a polypeptide of the present invention, preferably any of the polypeptides of SEQ Group 2 or a fragment thereof; or
  • (d) an antibody to a polypeptide of the present invention, preferably to the polypeptides of SEQ Group 2.
It will be appreciated that in any such kit, (a), (b), (c) or (d) may comprise a substantial component. Such a kit will be of use in diagnosing a disease or susceptibility to a Disease, among others.
This invention also relates to the use of polynucleotides of the present invention as diagnostic reagents. Detection of a mutated form of a polynucleotide of the invention, preferably any sequences of SEQ Group 1, which is associated with a disease or pathogenicity will provide a diagnostic tool that can add to, or define, a diagnosis of a disease, a prognosis of a course of disease, a determination of a stage of disease, or a susceptibility to a disease, which results from under-expression, over-expression or altered expression of the polynucleotide. Organisms, particularly infectious organisms, carrying mutations in such polynucleotide may be detected at the polynucleotide level by a variety of techniques, such as those described elsewhere herein.
Cells from an organism carrying mutations or polymorphisms (allelic variations) in a polynucleotide and/or polypeptide of the invention may also be detected at the polynucleotide or polypeptide level by a variety of techniques, to allow for serotyping, for example. For example, RT-PCR can be used to detect mutations in the RNA. It is particularly preferred to use RT-PCR in conjunction with automated detection systems, such as, for example, GeneScan. RNA, cDNA or genomic DNA may also be used for the same purpose, PCR. As an example, PCR primers complementary to a polynucleotide encoding BASB232 polypeptide can be used to identify and analyze mutations.
The invention further provides primers with 1, 2, 3 or 4 nucleotides removed from the 5′ and/or the 3′ end. These primers may be used for, among other things, amplifying BASB232 DNA and/or RNA isolated from a sample derived from an individual, such as a bodily material. The primers may be used to amplify a polynucleotide isolated from an infected individual, such that the polynucleotide may then be subject to various techniques for elucidation of the polynucleotide sequence. In this way, mutations in the polynucleotide sequence may be detected and used to diagnose and/or prognose the infection or its stage or course, or to serotype and/or classify the infectious agent.
The invention further provides a process for diagnosing, disease, preferably bacterial infections, more preferably infections caused by Bordetalla, particularly B. pertussis, comprising determining from a sample derived from an individual, such as a bodily material, an increased level of expression of polynucleotide having a sequence of any of the sequences of SEQ Group 1. Increased or decreased expression of a BASB232 polynucleotides can be measured using any on of the methods well known in the art for the quantitation of polynucleotides, such as, for example, amplification, PCR, RT-PCR, RNase protection, Northern blotting, spectrometry and other hybridization methods.
In addition, a diagnostic assay in accordance with the invention for detecting over-expression of BASB232 polypeptides compared to normal control tissue samples may be used to detect the presence of an infection, for example. Assay techniques that can be used to determine levels of BASB232 polypeptides, in a sample derived from a host, such as a bodily material, are well-known to those of skill in the art. Such assay methods include radioimmunoassays, competitive-binding assays, Western Blot analysis, antibody sandwich assays, antibody detection and ELISA assays.
The polynucleotides of the invention may be used as components of polynucleotide arrays, preferably high density arrays or grids. These high density arrays are particularly useful for diagnostic and prognostic purposes. For example, a set of spots each comprising a different gene, and further comprising a polynucleotide or polynucleotides of the invention, may be used for probing, such as using hybridization or nucleic acid amplification, using a probes obtained or derived from a bodily sample, to determine the presence of a particular polynucleotide sequence or related sequence in an individual. Such a presence may indicate the presence of a pathogen, particularly B. pertussis, and may be useful in diagnosing and/or prognosing disease or a course of disease. A grid comprising a number of variants of any polynucleotide sequences of SEQ Group 1 are preferred. Also preferred is a comprising a number of variants of a polynucleotide sequence encoding any polypeptide sequences of SEQ Group 2.
Antibodies
The polypeptides and polynucleotides of the invention or variants thereof, or cells expressing the same can be used as immunogens to produce antibodies immunospecific for such polypeptides or polynucleotides respectively. Alternatively, mimotopes, particularly peptide mimotopes, of epitopes within the polypeptide sequence may also be used as immunogens to produce antibodies immunospecific for the polypeptide of the invention. The term “immunospecific” means that the antibodies have substantially greater affinity for the polypeptides of the invention than their affinity for other related polypeptides in the prior art.
In certain preferred embodiments of the invention there are provided antibodies against BASB232 polypeptides or polynucleotides.
Antibodies generated against the polypeptides or polynucleotides of the invention can be obtained by administering the polypeptides and/or polynucleotides of the invention, or epitope-bearing fragments of either or both, analogues of either or both, or cells expressing either or both, to an animal, preferably a nonhuman, using routine protocols. For preparation of monoclonal antibodies, any technique known in the art that provides antibodies produced by continuous cell line cultures can be used. Examples include various techniques, such as those in Kohler, G. and Milstein, C., Nature 256: 495497 (1975); Kozbor et al, Immunology Today 4: 72 (1983); Cole et al., pg. 77-96 in MONOCLONAL ANTIBODIES AND CANCER THERAPY, Alan R. Liss, Inc. (1985).
Techniques for the production of single chain antibodies (U.S. Pat. No. 4,946,778) can be adapted to produce single chain antibodies to polypeptides or polynucleotides of this invention. Also, transgenic mice, or other organisms or animals, such as other mammals, may be used to express humanized antibodies immunospecific to the polypeptides or polynucleotides of the invention.
Alternatively, phage display technology may be utilized to select antibody genes with binding activities towards a polypeptide of the invention either from repertoires of PCR amplified v-genes of lymphocytes from humans screened for possessing anti-BASB232 or from naive libraries (McCafferty, et al., (1990), Nature 348, 552-554; Marks, et al., (1992) Biotechnology 10, 779-783). The affinity of these antibodies can also be improved by, for example, chain shuffling (Clackson et al., (1991) Nature 352: 628).
The above-described antibodies maybe employed to isolate or to identify clones expressing the polypeptides or polynucleotides of the invention to purify the polypeptides or polynucleotides by, for example, affinity chromatography.
Thus, among others, antibodies against BASB232 polypeptides or BASB232 polynucleotides maybe employed to treat infections, particularly bacterial infections.
Polypeptide variants include antigenically, epitopically or immunologically equivalent variants form a particular aspect of this invention.
Preferably, the antibody or variant thereof is modified to make it less immunogenic in the individual. For example, if the individual is human the antibody may most preferably be “humanized,” where the complimentarity determining region or regions of the hybridoma-derived antibody has been transplanted into a human monoclonal antibody, for example as described in Jones et al. (1986), Nature 321, 522-525 or Tempest et al, (1991) Biotechnology 9, 266-273.
Antagonists and Agonists—Assays and Molecules
Polypeptides and polynucleotides of the invention may also be used to assess the binding of small molecule substrates and ligands in, for example, cells, cell-free preparations, chemical libraries, and natural product mixtures. These substrates and ligands may be natural substrates and ligands or maybe structural or functional mimetics. See, e.g., Coligan et al., Current Protocols in Immunology 1(2): Chapter 5 (1991).
The screening methods may simply measure the binding of a candidate compound to the polypeptide or polynucleotide, or to cells or membranes bearing the polypeptide or polynucleotide, or a fusion protein of the polypeptide by means of a label directly or indirectly associated with the candidate compound. Alternatively, the screening method may involve competition with a labeled competitor. Further, these screening methods may test whether the candidate compound results in a signal generated by activation or inhibition of the polypeptide or polynucleotide, using detection systems appropriate to the cells comprising the polypeptide or polynucleotide. Inhibitors of activation are generally assayed in the presence of a known agonist and the effect on activation by the agonist by the presence of the candidate compound is observed. Constitutively active polypeptide and/or constitutively expressed polypeptides and polynucleotides may be employed in screening methods for inverse agonists or inhibitors, in the absence of an agonist or inhibitor, by testing whether the candidate compound results in inhibition of activation of the polypeptide or polynucleotide, as the case may be. Further, the screening methods may simply comprise the steps of mixing a candidate compound with a solution containing a polypeptide or polynucleotide of the present invention, to form a mixture, measuring BASB232 polypeptides and/or polynucleotides activity in the mixture, and comparing the BASB232 polypeptides and/or polynucleotides activity of the mixture to a standard. Fusion proteins, such as those made from Fc portion and BASB232 polypeptides, as hereinbefore described, can also be used for high-throughput screening assays to identify antagonists of the polypeptide of the present invention, as well as of phylogenetically and and/or functionally related polypeptides (see D. Bennett et al., J Mol Recognition, 8:52-58 (1995); and K Johanson et al., J Biol Chem, 270(16):9459-9471 (1995)).
The polynucleotides, polypeptides and antibodies that bind to and/or interact with a polypeptide of the present invention may also be used to configure screening methods for detecting the effect of added compounds on the production of mRNA and/or polypeptide in cells. For example, an ELISA assay may be constructed for measuring secreted or cell associated levels of polypeptide using monoclonal and polyclonal antibodies by standard methods known in the art. This can be used to discover agents which may inhibit or enhance the production of polypeptide (also called antagonist or agonist, respectively) from suitably manipulated cells or tissues.
The invention also provides a method of screening compounds to identify those which enhance (agonist) or block (antagonist) the action of BASB232 polypeptide or polynucleotides, particularly those compounds that are bacteriostatic and/or bactericidal. The method of screening may involve high-throughput techniques. For example, to screen for agonists or antagonists, a synthetic reaction mix, a cellular compartment, such as a membrane, cell envelope or cell wall, or a preparation of any thereof, comprising BASB232 polypeptide and a labeled substrate or ligand of such polypeptides is incubated in the absence or the presence of a candidate molecule that may be a BASB232 agonist or antagonist. The ability of the candidate molecule to agonize or antagonize the BASB232 polypeptide is reflected in decreased binding of the labeled ligand or decreased production of product from such substrate. Molecules that bind gratuitously, i.e., without inducing the effects of BASB232 polypeptide are most likely to be good antagonists. Molecules that bind well and, as the case may be, increase the rate of product production from substrate, increase signal transduction, or increase chemical channel activity are agonists. Detection of the rate or level of, as the case may be, production of product from substrate, signal transduction, or chemical channel activity may be enhanced by using a reporter system. Reporter systems that may be useful in this regard include but are not limited to colorimetric, labeled substrate converted into product, a reporter gene that is responsive to changes in BASB232 polynucleotide or polypeptide activity, and binding assays known in the art.
Another example of an assay for BASB232 agonists is a competitive assay that combines BASB232 and a potential agonist with BASB232 binding molecules, recombinant BASB232 binding molecules, natural substrates or ligands, or substrate or ligand mimetics, under appropriate conditions for a competitive inhibition assay. BASB232 can be labeled, such as by radioactivity or a colorimetric compound, such that the number of BASB232 molecules bound to a binding molecule or converted to product can be determined accurately to assess the effectiveness of the potential antagonist.
Potential antagonists include, among others, small organic molecules, peptides, polypeptides and antibodies that bind to a polynucleotide and/or polypeptide of the invention and thereby inhibit or extinguish its activity or expression. Potential antagonists also may be small organic molecules, a peptide, a polypeptide such as a closely related protein or antibody that binds the same sites on a binding molecule, such as a binding molecule, without inducing BASB232 induced activities, thereby preventing the action or expression of BASB232 polypeptides and/or polynucleotides by excluding BASB232 polypeptides and/or polynucleotides from binding.
Potential antagonists include a small molecule that binds to and occupies the binding site of the polypeptide thereby preventing binding to cellular binding molecules, such that normal biological activity is prevented. Examples of small molecules include but are not limited to small organic molecules, peptides or peptide-like molecules. Other potential antagonists include antisense molecules (see Okano, J. Neurochem. 56: 560 (1991); OLIGODEOXYNUCLEOTIDES AS ANTISENSE INHIBITORS OF GENE EXPRESSION, CRC Press, Boca Raton, Fla. (1988), for a description of these molecules). Preferred potential antagonists include compounds related to and variants of BASB232.
In a further aspect, the present invention relates to genetically engineered soluble fusion proteins comprising a polypeptide of the present invention, or a fragment thereof, and various portions of the constant regions of heavy or light chains of immunoglobulins of various subclasses (IgG, IgM, IgA, IgE). Preferred as an immunoglobulin is the constant part of the heavy chain of human IgG, particularly IgG1, where fusion takes place at the hinge region. In a particular embodiment, the Fc part can be removed simply by incorporation of a cleavage sequence which can be cleaved with blood clotting factor Xa. Furthermore, this invention relates to processes for the preparation of these fusion proteins by genetic engineering, and to the use thereof for drug screening, diagnosis and therapy. A further aspect of the invention also relates to polynucleotides encoding such fusion proteins. Examples of fusion protein technology can be found in International Patent Application Nos. WO94/29458 and WO94/22914.
Each of the polynucleotide sequences provided herein may be used in the discovery and development of antibacterial compounds. The encoded protein, upon expression, can be used as a target for the screening of antibacterial drugs. Additionally, the polynucleotide sequences encoding the amino terminal regions of the encoded protein or Shine-Delgarno or other translation facilitating sequences of the respective mRNA can be used to construct antisense sequences to control the expression of the coding sequence of interest.
The invention also provides the use of the polypeptide, polynucleotide, agonist or antagonist of the invention to interfere with the initial physical interaction between a pathogen or pathogens and a eukaryotic, preferably mammalian, host responsible for sequelae of infection. In particular, the molecules of the invention may be used: in the prevention of adhesion of bacteria, in particular Bordetella, to eukaryotic, preferably mammalian, extracellular matrix proteins on in-dwelling devices or to extracellular matrix proteins in wounds; to block bacterial adhesion between eukaryotic, preferably mammalian, extracellular matrix proteins and bacterial BASB232 proteins that mediate tissue damage and/or; to block the normal progression of pathogenesis in infections initiated other than by the implantation of in-dwelling devices or by other surgical techniques.
In accordance with yet another aspect of the invention, there are provided BASB232 agonists and antagonists, preferably bacteristatic or bactericidal agonists and antagonists.
The antagonists and agonists of the invention may be employed, for instance, to prevent, inhibit and/or treat diseases.
In a further aspect, the present invention relates to mimotopes of the polypeptide of the invention. A mimotope is a peptide sequence, sufficiently similar to the native antigen, preferably a peptide or LPS (sequentially or structurally), which is capable of being recognised by antibodies which recognise the native peptide; or is capable of raising antibodies which recognise the native peptide when coupled to a suitable carrier.
Peptide mimotopes may be designed for a particular purpose by addition, deletion or substitution of elected amino acids. Thus, the peptides may be modified for the purposes of ease of conjugation to a protein carrier. For example, it may be desirable for some chemical conjugation methods to include a terminal cysteine. In addition it may be desirable for peptides conjugated to a protein carrier to include a hydrophobic terminus distal from the conjugated terminus of the peptide, such that the free unconjugated end of the peptide remains associated with the surface of the carrier protein. Thereby presenting the peptide in a conformation which most closely resembles that of the peptide as found in the context of the whole native molecule. For example, the peptides may be altered to have an N-terminal cysteine and a C-terminal hydrophobic amidated tail. Alternatively, the addition or substitution of a D-stereoisomer form of one or more of the amino acids may be performed to create a beneficial derivative, for example to enhance stability of the peptide.
Alternatively, peptide mimotopes may be identified using antibodies which are capable themselves of binding to the polypeptides of the present invention using techniques such as phage display technology (EP 0 552 267 B1). This technique, generates a large number of peptide sequences which mimic the structure of the native peptides and are, therefore, capable of binding to anti-native peptide antibodies, but may not necessarily themselves share significant sequence homology to the native polypeptide.
Vaccines
Another aspect of the invention relates to a method for inducing an immunological response in an individual, particularly a mammal, preferably humans, which comprises inoculating the individual with BASB232 polynucleotide and/or polypeptide, or a fragment or variant thereof, or a combination thereof as described above, adequate to produce antibody and/or T cell immune response to protect said individual from infection, particularly bacterial infection and most particularly Bordetella infection including B. pertussis and/or B. parapertussis infection. Also provided are methods whereby such immunological response slows bacterial replication. Yet another aspect of the invention relates to a method of inducing immunological response in an individual which comprises delivering to such individual a nucleic acid vector, sequence or ribozyme to direct expression of BASB232 polynucleotide and/or polypeptide, or a fragment or a variant thereof, for expressing BASB232 polynucleotide and/or polypeptide, or a fragment or a variant thereof, or a combination thereof as described above, in vivo in order to induce an immunological response, such as, to produce antibody and/or T cell immune response, including, for example, cytokine-producing T cells or cytotoxic T cells, to protect said individual, preferably a human, from disease, whether that disease is already established within the individual or not. One example of administering the gene is by accelerating it into the desired cells as a coating on particles or otherwise. Such nucleic acid vector may comprise DNA, RNA, a ribozyme, a modified nucleic acid, a DNA/RNA hybrid, a DNA-protein complex or an RNA-protein complex.
A further aspect of the invention relates to an immunological composition that when iced into an individual, preferably a human, capable of having induced within it an immunological response, induces an immunological response in such individual to a BASB232 polynucleotide and/or polypeptide encoded therefrom, or a combination thereof as described above, wherein the composition comprises a recombinant BASB232 polynucleotide and/or polypeptide encoded therefrom and/or comprises DNA and/or RNA which encodes and expresses an antigen of said BASB232 polyncleotide, polypeptide encoded therefrom, or other polypeptide of the invention. The immunological response may be used therapeutically or prophylactically and may take the form of antibody immunity and/or cellular immunity, such as cellular immunity arising from CTL or CD4+ T cells.
A BASB232 polypeptide or a fragment thereof may be fused with co-protein or chemical moiety which may or may not by itself produce antibodies, but which is capable of stabilizing the first protein and producing a fused or modified protein which will have antigenic and/or immunogenic properties, and preferably protective properties. Thus fused recombinant protein, preferably further comprises an antigenic co-protein, such as lipoprotein D from Haemophilus influenzae, Glutathione-S-transferase (GST) or beta-galactosidase, or any other relatively large co-protein which solubilizes the protein and facilitates production and purification thereof. Moreover, the co-protein may act as an adjuvant in the sense of providing a generalized stimulation of the immune system of the organism receiving the protein. The co-protein may be attached to either the amino- or carboxy-terminus of the first protein.
In a vaccine composition according to the invention, a BASB232 polypeptide and/or polynucleotide, or a fragment, or a mimotope, or a variant thereof, or a combination thereof as described above, may be present in a vector, such as the live recombinant vectors described above for example live bacterial vectors.
Also suitable are non-live vectors for the BASB232 polypeptide, or a combination thereof as described above, for example bacterial outer-membrane vesicles or “blebs”. OM blebs are derived from the outer membrane of the two-layer membrane of Gram-negative bacteria and have been documented in many Gram-negative bacteria (Zhou, L et al. 1998. FEMS Microbiol. Lett. 163:223-228) including C. trachomatis and C. psittaci. A non-exhaustive list of bacterial pathogens reported to produce blebs also includes: Bordetella pertussis, Borrelia burgdorferi, Brucella melitensis, Brucella ovis, Esherichia coli, Haemophilus influenzae, Legionella pneumophila, Moraxella catarrhalis, Neisseria gonorrhoeae, Neisseria meningitides, Pseudomonas aeruginosa and Yersinia enterocolitica.
Blebs have the advantage of providing outer-membrane proteins in their native conformation and are thus particularly useful for vaccines. Blebs can also be improved for vaccine use by engineering the bacterium so as to modify the expression of one or more molecules at the outer membrane. Thus for example the expression of a desired immunogenic protein at the outer membrane, such as the BASB232 polypeptide, can be introduced or upregulated (e.g. by altering the promoter). Instead or in addition, the expression of outer-membrane molecules which are either not relevant (e.g. unprotective antigens or immunodominant but variable proteins) or detrimental (e.g. toxic molecules such as LPS, or potential inducers of an autoimmune response) can be downregulated. These approaches are discussed in more detail below.
The non-coding flanking regions of the BASB232 genes contain regulatory elements important in the expression of the gene. This regulation takes place both at the transcriptional and translational level. The sequence of these regions, either upstream or downstream of the open reading frame of the gene, can be obtained by DNA sequencing. This sequence information allows the determination of potential regulatory motifs such as the different promoter elements, terminator sequences, inducible sequence elements, repressors, elements responsible for phase variation, the shine-dalgarno sequence, regions with potential secondary structure involved in regulation, as well as other types of regulatory motifs or sequences. This sequence is a further aspect of the invention.
This sequence information allows the modulation of the natural expression of the BASB232 genes. The upregulation of the gene expression may be accomplished by altering the promoter, the shine-dalgarno sequence, potential repressor or operator elements, or any other elements involved. Likewise, downregulation of expression can be achieved by similar types of modification. Alternatively, by changing phase variation sequences, the expression of the gene can be put under phase variation control, or it may be uncoupled from this regulation. In another approach, the expression of the gene can be put under the control of one or more inducible elements allowing regulated expression. Examples of such regulation include, but are not limited to, induction by temperature shift, addition of inductor substrates like selected carbohydrates or their derivatives, trace elements, vitamins, co-factors, metal ions, etc.
Such modifications as described above can be introduced by several different means. The modification of sequences involved in gene expression can be carried out in vivo by random mutagenesis followed by selection for the desired phenotype. Another approach consists in isolating the region of interest and modifying it by random mutagenesis, or site-directed replacement, insertion or deletion mutagenesis. The modified region can then be reintroduced into the bacterial genome by homologous recombination, and the effect on gene expression can be assessed. In another approach, the sequence knowledge of the region of interest can be used to replace or delete all or part of the natural regulatory sequences. In this case, the regulatory region targeted is isolated and modified so as to contain the regulatory elements from another gene, a combination of regulatory elements from different genes, a synthetic regulatory region, or any other regulatory region, or to delete selected parts of the wild-type regulatory sequences. These modified sequences can then be reintroduced into the bacterium via homologous recombination into the genome. A non-exhaustive list of preferred promoters that could be used for up-regulation of gene expression includes the promoters porA, porB, lbpB, tbpB, p110, 1st, hpuAB from N. meningitidis or N. gonorroheae; ompCD, copB, lbpB, ompE, UspA1; UspA2; TbpB from M. Catarrhalis; p1, p2, p4, p5, p6, 1pD, tbpB, D15, Hia, Hmw1, Hmw2 from H. influenzae and any known strong promoter from B. pertussis or B. parapertussis. In one example, the expression of the gene can be modulated by exchanging its promoter with a stronger promoter (through isolating the upstream sequence of the gene, in vitro modification of this sequence, and reintroduction into the genome by homologous recombination). Upregulated expression can be obtained in both the bacterium as well as in the outer membrane vesicles shed (or made) from the bacterium.
In other examples, the described approaches can be used to generate recombinant bacterial strains with improved characteristics for vaccine applications. These can be, but are not limited to, attenuated strains, strains with increased expression of selected antigens, strains with knock-outs (or decreased expression) of genes interfering with the immune response, strains with modulated expression of immunodominant proteins, strains with modulated shedding of outer-membrane vesicles.
Thus, also provided by the invention is a modified upstream region of the BASB232 genes, which modified upstream region contains a heterologous regulatory element which alters the expression level of the BASB232 proteins located at the outer membrane. The upstream region according to this aspect of the invention includes the sequence upstream of the BASB232 genes. The upstream region starts immediately upstream of the BASB232 genes and continues usually to a position no more than about 1000 bp upstream of the gene from the ATG start codon. In the case of a gene located in a polycistronic sequence (operon) the upstream region can start immediately preceding the gene of interest, or preceding the first gene in the operon. Preferably, a modified upstream region according to this aspect of the invention contains a heterologous promotor at a position between 500 and 700 bp upstream of the ATG.
Thus, the invention provides BASB232 polypeptides, or a combination thereof as described above, in a modified bacterial bleb. The invention further provides modified host cells capable of producing the non-live membrane-based bleb vectors. The invention further provides nucleic acid vectors comprising the BASB232 genes having a modified upstream region containing a heterologous regulatory element.
Further provided by the invention are processes to prepare the host cells and bacterial blebs according to the invention.
Also provided by this invention are compositions, particularly vaccine compositions, and methods comprising the polypeptides and/or polynucleotides of the invention and immunostimulatory DNA sequences, such as those described in Sato, Y. et al. Science 273: 352 (1996).
Also, provided by this invention are methods using the described polynucleotide or particular fragments thereof, which have been shown to encode non-variable regions of bacterial cell surface proteins, in polynucleotide constructs used in such genetic immunization experiments in animal models of infection with B. pertussis. Such experiments will be particularly useful for identifying protein epitopes able to provoke a prophylactic or therapeutic immune response. It is believed that this approach will allow for the subsequent preparation of monoclonal antibodies of particular value, derived from the requisite organ of the animal successfully resisting or clearing infection, for the development of prophylactic agents or therapeutic treatments of bacterial infection, particularly B. pertussis infection, in mammals, particularly humans.
Immunogenic Compositions
It is advantageous for the antigens and combinations of antigens of the invention to be formulated into immunogenic compositions that comprise immunogenic, preferably immunologically effective, amounts of additional antigens to elicit immunity to other pathogens, preferably viruses and/or bacteria. Such additional antigens include diphtheria toxoid, tetanus toxoid, hepatitis B surface antigen, injectable polio vaccine, Haemophilus influenzae type b PRP, capsular polysaccharides or outer membranr vesicle preparations from N. meningitidis and capsular polysaccharides from S. pneumoniae.
Preferred immunogenic compositions of the invention are formulated with 1, 2, 3 or preferably all 4 of the following meningococcal capsular polysaccharides or oligosaccharides: A, C, Y or W, which may be plain or conjugated to a protein carrier.

Such a vaccine containing proteins from N. meningitidis serogroup B may be advantageously combine a global meningococcus vaccine with a Bordetella vaccine.
In a further preferred embodiment, the immunogenic compositions of the invention are formulated with a conjugated or unconjugated H. influenizae b capsular polysaccharide or oligosaccharide, and one or more plain or conjugated pneumococcal capsular polysaccharides or oligosaccarides.

In a further preferred embodiment, the immunogenic composition of the invention is formulated with capsular polysaccharides or oligosaccharides derived from one or more of Neisseria meningitidis, Haemophilus influenzae, Streptococcus pneumoniae, Group A Streptococci, Group B Streptococci, Staphylococcus aureus or Staphylococcus epidermidis. In a preferred embodiment, the immunogenic composition comprises capsular polysaccharides or oligosaccharides derived from one or more of serogroups A, C, W and Y of Neisseria meningitidis.

A further preferred embodiment comprises the capsular polysaccharides or oligosaccharides of Group A streptococcus, preferably further comprising at least one M protein and more preferably multiple types of M protein.
Capsular polysaccharides or oligosaccharides included in pharmaceutical compositions of the invention may be unconjugated or conjugated to a carrier protein such as tetanus toxoid, tetanus toxoid fragment C, non-toxic mutants of tetaus toxin, diphtheria toxoid, CRM197, other non-texic mutant of diphtheria toxin (such as CRM176, CRM197, CRM228, CRM45 (Uchida et al J. Biol. Chem. 218; 3838-3844, 1973); CRM9, CRM45, CRM102, CRM103 and CRM107 and other mutations described by Nicholls and Youle in Geneticaly Engineered Toxins, Ed: Frankel, Maecel Dekker Inc, 1992; deletion or mutation of Glu-148 to Asp, Gln or Ser and/or Ala 158 to Gly and other mutations disclosed in U.S. Pat.

No. 6,455,673; or fragment disclosed in U.S. Pat. No. 5,843,711), pneumolysin or Protein D (U.S. Pat. No. 6,342,224).
The polysaccharide conjugate may be prepared by any known coupling technique. For example the polysaccharide can be coupled via a thioether linkage. This conjugation method relies on activation of the polysaccharide with 1-cyano-4dimethylamino pyridinium tetrafluoroborate (CDAP) to form a cyanate ester. The activated polysaccharide may thus be coupled directly or via a spacer group to an amino group on the carrier protein. Preferably, the cyanate ester is coupled with hexane diamine and the amino-derivatised polysaccharide is conjugated to the carrier protein using heteroligation chemistry involving the formation of the thioether linkage. Such conjugates are described in PCT published application WO93/15760 Uniformed Services University.
The conjugates can also be prepared by direct reductive amination methods as described in U.S. Pat. No. 4,365,170 (Jernings) and U.S. Pat. No. 4,673,574 (Anderson). Other methods are described in EP-0-161-188, EP-208375 and EP-0-477508.
A further method involves the coupling of a cyanogen bromide activated polysaccharide derivatised with adipic acid hydrazide (ADH) to the protein carrier by Carbodiimide condensation (Chu C. et al Infect. Immunity, 1983 245 256).

Vaccines
A further embodiment of the invention provides a vaccine formulation which comprises an immunogenic recombinant polypeptide and/or polynucleotide of the invention, or a combination thereof, together with a suitable carrier/excipient, such as a pharmaceutically acceptable carrier/excipient. Since the polypeptides and polynucleotides may be broken down in the stomach, each is preferably administered parenterally, including, for example, administration that is subcutaneous, intramuscular, intravenous, or intradermal.
Formulations suitable for parenteral administration include aqueous and non-aqueous sterile injection solutions which may contain anti-oxidants, buffers, bacteriostatic compounds and solutes which render the formulation isotonic with the bodily fluid, preferably the blood, of the individual; and aqueous and non-aqueous sterile suspensions which may include suspending agents or thickening agents. The formulations may be presented in unit-dose or multi-dose containers, for example, sealed ampoules and vials and may be stored in a freeze-dried condition requiring only the addition of the sterile liquid carrier immediately prior to use.
The vaccine formulation of the invention may also include adjuvant systems for enhancing the immunogenicity of the formulation. The adjuvant may be aluminium hydroxide, aluminium phosphate or a mixture of aluminium hydroxide and aluminium phosphate. Where hepatitis B surface antigen is present as part of the vaccine, the adjuvant is preferably aluminium phosphate. Preferably the adjuvant system raises preferentially a TH1 type of response.
An immune response may be broadly distinguished into two extreme catagories, being a humoral or cell mediated immune responses (traditionally characterised by antibody and cellular effector mechanisms of protection respectively). These categories of response have been termed TH1-type responses (cell-mediated response), and TH2-type immune responses (humoral response).
Extreme TH1-type immune responses maybe characterised by the generation of antigen specific, haplotype restricted cytotoxic T lymphocytes, and natural killer cell responses. In mice TH1-type responses are often characterised by the generation of antibodies of the IgG2a subtype, whilst in the human these correspond to IgG1 type antibodies. TH2-type immune responses are characterised by the generation of a broad range of immunoglisotypes including in mice IgG1, IgA, and IgM.
It can be considered that the driving force behind the development of these two types of immune responses are cytokines. High levels of TH1-type cytokines tend to favour the induction of cell mediated immune responses to the given antigen, whilst high levels of TH2-type cytokines tend to favour the induction of humoral immune responses to the antigen.
The distinction of TH1 and TH2-type immune responses is not absolute. In reality an individual will support an immune response which is described as being predominantly TH1 or predominantly TH2. However, it is often convenient to consider the families of cytolines in terms of that described in murine CD4+ ve T cell clones by Mosmann and Coffman (Mosmann, T. R. and Coffman, R. L. (1989) TH1 and TH2 cells: different patterns of lymphokine secretion lead to different functional properties. Annual Review of Immunology, 7, p145-173). Traditionally, TH1-type responses are associated with the production of the INF-γ and IL-2 cytokines by T-lymphocytes. Other cytokines often directly associated with the induction of TH1-type immune responses are not produced by T-cells, such as IL-12. In contrast, TH2-type responses are associated with the secretion of IL-4, IL-5, IL-6 and IL-13.
It is known that certain vaccine adjuvants are particularly suited to the stimulation of either TH1 or TH2-type cytokine responses. Traditionally the best indicators of the TH1:TH2 balance of the immune response after a vaccination or infection includes direct measurement of the production of TH1 or TH2 cytokines by T lymphocytes in vitro after restimulation with antigen, and/or the measurement of the IgG1:IgG2a ratio of antigen specific antibody responses.
Thus, a TH1-type adjuvant is one which preferentially stimulates isolated T-cell populations to produce high levels of TH1-type cytokines when re-stimulated with antigen in vitro, and promotes development of both CD8+ cytotoxic T lymphocytes and antigen specific immunoglobulin responses associated with TH1-type isotype.
Adjuvants which are capable of preferential stimulation of the TH1 cell response are described in International Patent Application No. WO 94/00153 and WO 95/17209.
3 De-O-acylated monophosphoryl lipid A (3D-MPL) is one such adjuvant. This is known from GB 2220211 (Ribi). Chemically it is a mixture of 3 De-O-acylated monophosphoryl lipid A with 4, 5 or 6 acylated chains and is manufactured by Ribi Immunochem, Montana. A preferred form of 3 De-O-acylated monophosphoryl lipid A is disclosed in European Patent 0 689 454 B1 (SmithKline Beecham Biologicals SA).
Preferably, the particles of 3D-MPL are small enough to be sterile filtered through a 0.22 micron membrane (European Patent number 0 689 454).
3D-MPL will be present in the range of 10 μg-100 μg preferably 25-50 μg per dose wherein the antigen will typically be present in a range 2-50 μg per dose.
Another preferred adjuvant comprises QS21, an Hplc purified non-toxic fraction derived from the bark of Quillaja Saponaria Molina. Optionally this may be admixed with 3 De-O-acylated monophosphoryl lipid A (3D-MPL), optionally together with an carrier.
The method of production of QS21 is disclosed in U.S. Pat. No. 5,057,540.
Non-reactogenic adjuvant formulations containing QS21 have been described previously (WO 96/33739). Such formulations comprising QS21 and cholesterol have been shown to be successful TH1 stimulating adjuvants when formulated together with an antigen.
Further adjuvants which are preferential stimulators of TH1 cell response include immunomodulatory oligonucleotides, for example unmethylated CpG sequences as disclosed in WO 96/02555.
Combinations of different TH1 stimulating adjuvants, such as those mentioned hereinabove, are also contemplated as providing an adjuvant which is a preferential stimulator of TH1 cell response. For example, QS21 can be formulated together with 3D-MPL. The ratio of QS21: 3D-MPL will typically be in the order of 1:10 to 10:1; preferably 1:5 to 5:1 and often substantially 1:1. The preferred range for optimal synergy is 2.5:1 to 1:1 3D-MPL: QS21.
Preferably a carrier is also present in the vaccine composition according to the invention. The carrier may be an oil in water emulsion, or an aluminium salt, such as aluminium phosphate or aluminium hydroxide.
A preferred oil-in-water emulsion comprises a metabolisible oil, such as squalene, alpha tocopherol and Tween 80. In a particularly preferred aspect the antigens in the vaccine composition according to the invention are combined with QS21 and 3D-MPL in such an emulsion. Additionally the oil in water emulsion may contain span 85 and/or lecithin and/or tricaprylin.
Typically for human administration QS21 and 3D-MPL will be present in a vaccine in the range of 1 μg-200 μg, such as 10-100 μg, preferably 10 μg-50 μg per dose. Typically the oil in water will comprise from 2 to 10% squalene, from 2 to 10% alpha tocopherol and from 0.3 to 3% tween 80. Preferably the ratio of squalene: alpha tocopherol is equal to or less than 1 as this provides a more stable emulsion. Span 85 may also be present at a level of 1%. In some cases it may be advantageous that the vaccines of the present invention will further contain a stabiliser.
Non-toxic oil in water emulsions preferably contain a non-toxic oil, e.g. squalane or squalene, an emulsifier, e.g. Tween 80, in an aqueous carrier. The aqueous carrier may be, for example, phosphate buffered saline.
A particularly potent adjuvant formulation involving QS21, 3D-MPL and tocopherol in an oil in water emulsion is described in WO 95/17210.
While the invention has been described with reference to certain BASB232 polypeptides and polynucleotides, it is to be understood that this covers fragments of the naturally occurring polypeptides and polynucleotides, and similar polypeptides and polynucleotides with additions, deletions or substitutions which do not substantially affect the immunogenic properties of the recombinant polypeptides or polynucleotides.
Compositions, Kits and Administration In a further aspect of the invention there are provided compositions comprising a BASB232 polynucleotide and/or a BASB232 polypeptide for administration to a cell or to a multicellular organism.
The invention also relates to compositions comprising a polynucleotide and/or a polypeptides discussed herein or their agonists or antagonists. The polypeptides and polynucleotides of the invention maybe employed in combination with a non-sterile or sterile carrier or carriers for use with cells, tissues or organisms, such as a pharmaceutical carrier suitable for administration to an individual. Such compositions comprise, for instance, a media additive or a therapeutically effective amount of a polypeptide and/or polynucleotide of the invention and a pharmaceutically acceptable carrier or excipient. Such carriers may include, but are not limited to, saline, buffered saline, dextrose, water, glycerol, ethanol and combinations thereof. The formulation should suit the mode of administration. The invention further relates to diagnostic and pharmaceutical packs and kits comprising one or more containers filled with 1, 2, 3, 4 or 5 of the ingredients of the aforementioned compositions of the invention.
Polypeptides, polynucleotides and other compounds of the invention may be employed alone or in conjunction with other compounds, such as therapeutic compounds.
The pharmaceutical compositions may be administered in any effective, convenient manner including, for instance, administration by topical, oral, anal vaginal, intravenous, intraperitoneal, intramuscular, subcutaneous, intranasal or intradermal routes among others.
In therapy or as a prophylactic, the active agent may be administered to an individual as an injectable composition, for example as a sterile aqueous dispersion, preferably isotonic.
In a further aspect, the present invention provides for pharmaceutical compositions comprising a therapeutically effective amount of a polypeptide and/or polynucleotide, such as the soluble form of a polypeptide and/or polynucleotide of the present invention, agonist or antagonist peptide or small molecule compound, in combination with a pharmaceutically acceptable carrier or excipient. Such carriers include, but are not limited to, saline, buffered saline, dextrose, water, glycerol, ethanol, and combinations thereof. The invention further relates to pharmaceutical packs and kits comprising one or more containers filled with one or more of the ingredients of the aforementioned compositions of the invention. Polypeptides, polynucleotides and other compounds of the present invention may be employed alone or in conjunction with other compounds, such as therapeutic compounds.
The composition will be adapted to the route of administration, for instance by a systemic or an oral route. Preferred forms of systemic administration include injection, typically by intravenous injection. Other injection routes, such as subcutaneous, intramuscular, or intraperitoneal, can be used. Alternative means for systemic administration include transmucosal and transdermal administration using penetrants such as bile salts or fusidic acids or other detergents. In addition, if a polypeptide or other compounds of the present invention can be formulated in an enteric or an encapsulated formulation, oral administration may also be possible. Administration of these compounds may also be topical and/or localized, in the form of salves, pastes, gels, solutions, powders and the like.
For administration to mammals, and particularly humans, it is expected that the daily dosage level of the active agent will be from 0.01 mg/kg to 10 mg/kg, typically around 1 mg/kg. The physician in any event will determine the actual dosage which will be most suitable for an individual and will vary with the age, weight and response of the particular individual. The above dosages are exemplary of the average case. There can, of course, be individual instances where higher or lower dosage ranges are merited, and such are within the scope of this invention.
The dosage range required depends on the choice of peptide, the route of administration, the nature of the formulation, the nature of the subject's condition, and the judgment of the attending practitioner. Suitable dosages, however, are in the range of 0.1-100 μg/kg of subject.
A vaccine composition is conveniently in injectable form. Conventional adjuvants may be employed to enhance the immune response. A suitable unit dose for vaccination is 0.5-5 microgram/kg of antigen, and such dose is preferably administered 1-3 times and with an interval of 1-3 weeks. With the indicated dose range, no adverse toxicological effects will be observed with the compounds of the invention which would preclude their administration to suitable individuals.
Wide variations in the needed dosage, however, are to be expected in view of the variety of compounds available and the differing efficiencies of various routes of administration. For example, oral administration would be expected to require higher dosages than administration by intravenous injection. Variations in these dosage levels can be adjusted using standard empirical routines for optimization, as is well understood in the art.

Definitions
“Identity,” as known in the art, is a relationship between two or more polypeptide sequences or two or more polynucleotide sequences, as the case may be, as determined by comparing the sequences. In the art, “identity” also means the degree of sequence relatedness between polypeptide or polynucleotide sequences, as the case may be, as determined by the match between strings of such sequences. “Identity” can be readily calculated by known methods, including but not limited to those described in (Computational Molecular Biology, Lesk, A. M., ed., Oxford University Press, New York, 1988; Biocomputing: Informatics and Genome Projects, Smith, D. W., ed., Academic Press, New York, 1993; Computer Analysis of Sequence Data, Part I, Griffin, A. M., and Griffin, H. G., eds., Humana Press, New Jersey, 1994; Sequence Analysis in Molecular Biology, von Heine, G., Academic Press, 1987; and Sequence Analysis Primer, Gribskov, M. and Devereux, J., eds., M Stockton Press, New York, 1991; and Carillo, H., and Lipman, D., SIAM J. Applied Math., 48: 1073 (1988). Methods to determine identity are designed to give the largest match between the sequences tested. Moreover, methods to determine identity are codified in publicly available computer programs. Computer program methods to determine identity between two sequences include, but are not limited to, the GAP program in the GCG program package (Devereux, J., et al., Nucleic Acids Research 12(1): 387 (1984)), BLASTP, BLASTN (Altschul, S.

(1) Polynucleotide embodiments further include an isolated polynucleotide comprising a polynucleotide sequence having at least a 50, 60, 70, 80, 85, 90, 95, 97 or 100% identity to the reference sequence of SEQ ID NO: 1, wherein said polynucleotide sequence may be identical to the reference sequence of SEQ ID NO:1 or may include up to a certain integer number of nucleotide alterations as compared to the reference sequence, wherein said alterations are selected from the group consisting of at least one nucleotide deletion, substitution, including transition and transversion, or insertion, and wherein said alterations may occur at the 5′ or 3′ terminal positions of the reference nucleotide sequence or anywhere between those terminal positions, interspersed either individually among the nucleotides in the reference sequence or in one or more contiguous groups within the reference sequence, and wherein said number of nucleotide alterations is determined by multiplying the total number of nucleotides in SEQ ID NO:1 by the integer defining the percent identity divided by 100 and then subtracting that product from said total number of nucleotides in SEQ ID NO:1, or:
n n ≦x n−(x n ·y),
wherein nn is the number of nucleotide alterations, xn is the total number of nucleotides in SEQ ID NO:1, y is 0.50 for 50%, 0.60 for 60%, 0.70 for 70%, 0.80 for 80%, 0.85 for 85%, 0.90 for 90%, 0.95 for 95%, 0.97 for 97% or 1.00 for 100%, and · is the symbol for the multiplication operator, and wherein any non-integer product of xn and y is rounded down to the nearest integer prior to subtracting it from xn. Alterations of a polynucleotide sequence encoding the polypeptide of SEQ ID NO:2 may create nonsense, missense or frameshift mutations in this coding sequence and thereby alter the polypeptide encoded by the polynucleotide following such alterations.
By way of example, a polynucleotide sequence of the present invention may be identical to the reference sequence of SEQ ID NO:1, that is it may be 100% identical, or it may include up to a certain integer number of nucleic acid alterations as compared to the reference sequence such that the percent identity is less than 100% identity. Such alterations are selected from the group consisting of at least one nucleic acid deletion, substitution, including transition and transversion, or insertion, and wherein said alterations may occur at the 5′ or 3′ terminal positions of the reference polynucleotide sequence or anywhere between those terminal positions, interspersed either individually among the nucleic acids in the reference sequence or in one or more contiguous groups within the reference sequence. The number of nucleic acid alterations for a given percent identity is determined by multiplying the total number of nucleic acids in SEQ ID NO:1 by the integer defining the percent identity divided by 100 and then subtracting that product from said total number of nucleic acids in SEQ ID NO:1, or:
n n ≦x n−(x n ·y),
wherein nn is the number of nucleic acid alterations, xn is the total number of nucleic acids in SEQ ID NO:1, y is, for instance 0.70 for 70%, 0.80 for 80%, 0.85 for 85% etc., · is the symbol for the multiplication operator, and wherein any non-integer product of xn and y is rounded down to the nearest integer prior to subtracting it from xn.
(2) Polypeptide embodiments further include an isolated polypeptide comprising a polypeptide having at least a 50, 60, 70, 80, 85, 90, 95, 97 or 100% identity to a polypeptide reference sequence of SEQ ID NO:2, wherein said polypeptide sequence may be identical to the reference sequence of SEQ ID NO:2 or may include up to a certain integer number of amino acid alterations as compared to the reference sequence, wherein said alterations are selected from the group consisting of at least one amino acid deletion, substitution, including conservative and non-conservative substitution, or insertion, and wherein said alterations may occur at the amino- or carboxy-terminal positions of the reference polypeptide sequence or anywhere between those terminal positions, interspersed either individually among the amino acids in the reference sequence or in one or more contiguous groups within the reference sequence, and wherein said number of amino acid alterations is determined by multiplying the total number of amino acids in SEQ ID NO:2 by the integer defining the percent identity divided by 100 and then subtracting that product from said total number of amino acids in SEQ ID NO:2, or:
n a ≦x a−(x a ·y),
wherein na is the number of amino acid alterations, xa is the total number of amino acids in SEQ ID NO:2, y is 0.50 for 50%, 0.60 for 60%, 0.70 for 70%, 0.80 for 80%, 0.85 for 85%, 0.90 for 90%, 0.95 for 95%, 0.97 for 97% or 1.00 for 100%, and · is the symbol for the multiplication operator, and wherein any non-integer product of xa and y is rounded down to the nearest integer prior to subtracting it from xa.
By way of example, a polypeptide sequence of the present invention may be identical to the reference sequence of SEQ ID NO:2, that is it may be 100% identical, or it may include up to a certain integer number of amino acid alterations as compared to the reference sequence such that the percent identity is less than 100% identity. Such alterations are selected from the group consisting of at least one amino acid deletion, substitution, including conservative and non-conservative substitution, or insertion, and wherein said alterations may occur at the amino- or carboxy-terminal positions of the reference polypeptide sequence or anywhere between those terminal positions, interspersed either individually among the amino acids in the reference sequence or in one or more contiguous groups within the reference sequence. The number of amino acid alterations for a given % identity is determined by multiplying the total number of amino acids in SEQ ID NO:2 by the integer defining the percent identity divided by 100 and then subtracting that product from said total number of amino acids in SEQ ID NO:2, or:
n a ≦x a−(x a ·y),
wherein na is the number of amino acid alterations, xa is the total number of amino acids in SEQ ID NO:2, y is, for instance 0.70 for 70%, 0.80 for 80%, 0.85 for 85% etc., and · is the symbol for the multiplication operator, and wherein any non-integer product of xa and y is rounded down to the nearest integer prior to subtracting it from xa.
The terms “comprising”, “comprise” and “comprises” herein is intended by the inventors to be optionally substitutable with the terms “consisting of”, “consist of”, and “consists of”, respectively, in every instance.
“Immunogenic composition” in the context of a polynucleotide means that when the polynucleotide is introduced into a host and protein is expresssed from that polynucleotide, the expressed protein is immunogenic.
“Individual(s),” when used herein with reference to an organism, means a multicellular eukaryote, including, but not limited to a metazoan, a mammal, an ovid, a bovid, a simian, a primate, and a human.
“Isolated” means altered “by the hand of man” from its natural state, i.e., if it occurs in nature, it has been changed or removed from its original environment, or both. For example, a polynucleotide or a polypeptide naturally present in a living organism is not “isolated,” but the same polynucleotide or polypeptide separated from the coexisting materials of its natural state is “isolated”, as the term is employed herein. Moreover, a polynucleotide or polypeptide that is introduced into an organism by transformation, genetic manipulation or by any other recombinant method is “isolated” even if it is still present in said organism, which organism may be living or non-living.
“Polynucleotide(s)” generally refers to any polyribonucleotide or polydeoxyribonucleotide, which maybe unmodified RNA or DNA or modified RNA or DNA including single and double-stranded regions.
“Toxin” preferably includes a toxoid form of the toxin.
“Variant” refers to a polynucleotide or polypeptide that differs from a reference polynucleotide or polypeptide, but retains essential properties. A typical variant of a polynucleotide differs in nucleotide sequence from another, reference polynucleotide. Changes in the nucleotide sequence of the variant may or may not alter the amino acid sequence of a polypeptide encoded by the reference polynucleotide. Nucleotide changes may result in amino acid substitutions, additions, deletions, fusions and truncations in the polypeptide encoded by the reference sequence, as discussed below. A typical variant of a polypeptide differs in ammo acid sequence from another, reference polypeptide. Generally, differences are limited so that the sequences of the reference polypeptide and the variant are closely similar overall and, in many regions, identical. A variant and reference polypeptide may differ in amino acid sequence by one or more substitutions, additions, deletions in any combination. A substituted or inserted amino acid residue may or may not be one encoded by the genetic code. A variant of a polynucleotide or polypeptide may be a naturally occurring such as an allelic variant, or it may be a variant that is not known to occur naturally. Non-naturally occurring variants of polynucleotides and polypeptides may be made by mutagenesis techniques or by direct synthesis.
“Disease(s)” means any disease caused by or related to infection by a bacteria, including, for example, otitis media in infants and children, pneumonia in elderlies, sinusitis, nosocomial infections and invasive diseases, chronic otitis media with hearing loss, fluid accumulation in the middle ear, auditive nerve damage, delayed speech learning, infection of the upper respiratory tract and inflammation of the middle ear.
EXAMPLES
The examples below are carried out using standard techniques, which are well known and routine to those of skill in the art, except where otherwise described in detail. The examples are illustrative, but do not limit the invention.
Example 1 Cloning of the BASB232 Genes B. Pertussis Strain Tohama I
Genomic DNA is extracted from the B. pertussis strain Tohama I from 1010 bacterial cells using the QIAGEN genomic DNA extraction kit (Qiagen Gmbh). This material (1 μg) is then submitted to Polymerase Chain Reaction DNA amplification using two specific primers. A DNA fragment is obtained, digested by the suitable restriction endonucleases and inserted into the compatible sites of the pET cloning/expression vector (Novagen) using standard molecular biology techniques (Molecular Cloning, a Laboratory Manual, Second Edition, Eds: Sambrook, Fritsch & Maniatis, Cold Spring Harbor press 1989). Recombinant pET-BASB232 is then submitted to DNA sequencing using the Big Dyes kit (Applied biosystems) and analyzed on a ABI 373/A DNA sequencer in the conditions described by the supplier.
Example 2 Expression and Purification of Recombinant BASB232 Proteins in Escherichia coli
The construction of the pET-BASB232 cloning/expression vector is described in Example 1. This vector harbours the BASB232 gene isolated from Bordetella pertussis strain Tohama I in fusion with a stretch of 6 Histidine residues, placed under the control of the strong bacteriophage T7 gene 10 promoter. For expression study, this vector is introduced into the Escherichia coli strain Novablue DE3) (Novagen), in which, the gene for the T7 polymerase is placed under the control of the isopropyl-beta-D thiogalactoside (IPTG)-regulatable lac promoter. Liquid cultures (100 ml) of the Novablue (DE3) [pET-BASB232] E. coli recombinant strain are grown at 37° C. under agitation until the optical density at 600 nm (OD600) reached 0.6. At that time-point, IPTG is added at a final concentration of 1 mM and the culture is grown for 4 additional hours. The culture is then centrifuged at 10,000 rpm and the pellet is frozen at −20° C. for at least 10 hours. After thawing, the pellet is resuspended during 30 min at 25° C. in buffer A (6M guanidine hydrochloride, 0.1M NaH2PO4, 0.01M Tris, pH 8.0), passed three-times through a needle and clarified by centrifigation (20000 rpm, 15 min). The sample is then loaded at a flow-rate of 1 ml/min on a Ni2+-loaded Hitrap column (Pharmacia Biotech). After passsage of the flowthrough, the column is washed succesively with 40 ml of buffer B (8M Urea, 0.1MNaH2PO4, 0.01M Tris, pH 8.0), 40 ml of buffer C (8M Urea, 0.1MNaH2PO4, 0.01M Tris, pH 6.3). The recombinant protein BASB232/His6 is then eluted from the column with 30 ml of buffer D (8M Urea, 0.1MNaH2PO4, 0.01M Tris, pH 6.3) containing 500 mM of imidazole and 3 ml-size fractions are collected. Highly enriched BASB232/His6 protein can be eluted from the column. This polypeptide is detected by a mouse monoclonal antibody raised against the 5-histidine motif. Moreover, the denatured, recombinant BASB232-His6 protein is solubilized in a solution devoid of urea. For this purpose, denatured BASB232-His6 contained in 8M urea is extensively dialyzed (2 hours) against buffer R (NaCl 150 mM, 10 mM NaH2PO4, Arginine 0.5M pH6.8) containing successively 6M, 4M, 2M and no urea. Alternatively, this polypeptide is purified under non-denaturing conditions using protocoles described in the Quiexpresssionist booklet (Qiagen Gmbh).
Example 3 Production of Antisera to Recombinants BASB232
Polyvalent antisera directed against the BASB232 protein are generated by vaccinating rabbits with the purified recombinant BASB232 protein. Polyvalent antisera directed against the BASB232 protein are also generated by vaccinating mice with the purified recombinant BASB232 protein. Animals are bled prior to the first immunication (“pre-bleed”) and after the last immunization.
Anti-BASB232 protein titers are measured by an ELISA using purified recombinant BASB232 protein as the coating antigen. The titer is defined as mid-point titers calculated by 4-parameter logistic model using the XL Fit software. The antisera are also used as the first antibody to identify the protein in a western blot as described in example 5 below.
Example 4 Immunological characterization: Surface Exposure of BASB232
Anti-BASB232 proteins titres are determined by an ELISA using formalin-killed whole cells of Boydetella pertussis (B.pertussis). The titer is defined as mid-point titers calculated by 4-parameter logistic model using the XL Fit software.
Example 5 Immunological Characterisation: Western Blot Analysis
Several strains of B.pertussis, as well as clinical isolates, are grown on Bordet Gengou agar plates for 24 hours at 36° C. and 5% CO2. Several colonies are used to inoculate Tryptic Soy Agar (TSA) broth supplemented by NAD and hemin, each at 10 μg/ml. Cultures are grown until the absorbance at 620 nm is approximately 0.4 and cells are collected by centrifugation. Cells are then concentrated and solubilized in PAGE sample buffer. The solubilized cells are then resolved on 4-20% polyacrylamide gels and the separated proteins are electrophoretically transferred to PVDF membranes. The PVDF membranes are then pretreated with saturation buffer. All subsequent incubations are carried out using this pretreatment buffer.
PVDF membranes are incubated with preimmune serum and rabbit or mouse immune seruum PVDF membranes are then washed.
PVDF membranes are incubated with biotin-labeled sheep anti-rabbit or mouse Ig. PVDF membranes are then washed 3 times with wash buffer, and incubated with streptavidin-peroxydase. PVDF membranes are then washed 3 times with wash buffer and developed with 4-chloro-1-naphtol.
Example 6 Presence of Antibody to BASB232 in Human Convalescent Sera
Western blot analysis of purified recombinant BASB232 is performed as described in Example 5 above, except that a pool of human sera from children infected by B.pertussis is used as the first antibody preparation.
Example 7 Efficacy of BASB232 Vaccine: Enhancement of Lung Clearance of B.pertussis in Mice
This mouse model is based on the analysis of the lung invasion by B.pertussis following a standard intranasal challenge to vaccinated mice.
Groups of mice are immunized with BASB232 vaccine. After the booster, the mice are challenged by instillation of bacterial suspension into the nostril under anaesthesia. Mice are killed between 30 minutes as well as 2, 5 and 8 days after challenge and the lungs are removed aseptically and homogenized individually. The log10 weighted mean number of CFU/lung is determined by counting the colonies grown on agar plates after plating of dilutions of the homogenate. The arithmetic mean of the log10 weighted mean number of CFU/lung and the standard deviations are calculated for each group. Results are analysed statistically.
In this experiment groups of mice are immunized either with BASB232 or with a killed whole cells (kwc) preparation of B.pertussis or sham immunized.
Example 8 Useful Epitopes
The B-cell epitopes of a protein are mainly localized at its surface. To predict B-cell epitopes of BASB232 polypeptides two methods were combined: 2D-structure prediction and antigenic index prediction. The 2D-structure prediction was made using the PSIPRED program (from David Jones, Brunel Bioinformatics Group, Dept. Biological Sciences, Brunel University, Uxbridge UB8 3PH, UK). The antigenic index was calculated on the basis of the method described by Jameson and Wolf (CABIOS 4:181-186 [1988]). The parameters used in this program are the antigenic index and the minimal length for an antigenic peptide. An antigenic index of 0.9 for a minimum of 5 consecutive amino acids was used as threshold in the program. Peptides comprising good, potential B-cell epitopes are listed in table 5. These can be useful (preferably conjugated or recombinantly joined to a larger protein) in a vaccine composition for the prevention of Bordetella infections, as could similar peptides comprising conservative mutations (preferably 70, 80, 95, 99 or 100% identical to the sequences of table 5) or truncates comprising 5 or more (e.g. 6, 7, 8, 9, 10, 11 or 12) amino acids therefrom or extensions comprising e. g. 1, 2, 3, 5, 10 further amino acids at either or both ends from the native context of BASB232 polypeptides which preserve an effective epitope which can elicit an immune response in a host against the BASB232 polypeptides.

The T-helper cell epitopes are peptides bound to HLA class II molecules and recognized by T-helper cells. The prediction of useful T-helper cell epitopes of BASB232 polypeptides was based on the TEPITOPE method describe by Sturniolo at al. (Nature Biotech. 17: 555-561 [1999]). Peptides comprising good, potential T-cell epitopes are listed in table 6. These can be useful (preferably conjugated to peptides, polypeptides or polysaccharides) for vaccine purposes, as could similar peptides comprising conservative mutations (preferably 70, 80, 95, 99 or 100% identical to the sequences below) or truncates comprising 5 or more (e.g. 6, 7, 8, 9, 10, 11, 12, 14, 16, 18 or 20) amino acids therefrom or extensions comprising e. g. 1, 2, 3, 5, 10 further amino acids at either or both ends from the native context of BASB232 polypeptides which preserve an effective T-helper epitope from BASB232 polypeptides.

Example 9 Expression of BrkA
BrkA is a 1010 amino acid protein. A pET30b expression vector containing amino acids 60-702 of BrkA, fused at the C and N-terminal to a 6×-His tag was used to express BrkA in E. coli. The bacteria were grown to an OD600 of approximately 0.6 and induced with 1 mM IPTG for 2 hours. Recombinant BrkA was purified under denaturing conditions using the protocol in the Xpress System Protein Purification manual (Invitrogen, Carlsbad, Calif.). The bacteria were lysed in 6M guanidine hydrochloride and the lysate was applied to to Ni2+-nitrilotriacetic acid agarose (Qiagen, Mississauga, Ont.). After successive washes in 8M urea of decreasing pH, purified BrkA was eluted at pH 4 and the fractions were pooled. The urea was removed by slow dialysis at 4° C. against 10 mM Tris, pH 8.0 in the presence of 0.1% Triton X-100.
The purified protein was refolded so that it has a beta-structure resembling PRN (monitored by CD) and was functional in a serum assay. The protein was filter sterilized and is diluted in 10 mM Tris buffer, pH 8 at a concentration of approximately 0.4 mg/ml.
Example 10 Formulation of Vaccines
Six vaccines were formulated:
    • 1. DTPa018A2—contains 6.25Lf DT, 2.5Lf TT, 6.25 ug PT and 6.25 ug FHA per mouse dose. All antigens were adsorbed separately onto Al(OH)3 before combining.
    • 2. DTPa14885B9—contains 6.25Lf DT, 2.5Lf TT, 6.25 ug PT, 6.25 ug FHA and 2 ug pertactin per mouse dose. All antigens were adsorbed separately onto Al(OH)3 before combining.
    • 3. DTPw13126A9—contains 6.25Lf DT, 2.5Lf TT and 1 I.U.whole cell B. pertussis per mouse dose. All antigens were adsorbed separately onto Al(OH)3 before combining.
    • 4. DTBrkA—contains 6.25Lf DT, 2.5Lf TT and 2.5 ug BrkA per mouse dose. All antigens were adsorbed separately onto Al(OH)3 before combining.
    • 5. DTPa-2 BrkA—contains 6.25Lf DT, 2.5Lf TT, 6.25 ug PT, 6.25 ug FHA and 2.5 ug BrkA per mouse dose. All antigens were adsorbed separately onto Al(OH)3 before combining.
    • 6. DTPa-3 BrkA—contains 6.25Lf DT, 2.5Lf TT, 6.25 ug PT, 6.25 ug FHA, 2 ug pertactin and 2.5 ug BrkA per mouse dose. All antigens were adsorbed separately onto Al(OH)3 before combining.
Example 11 Protection Against Lung Invasion by B. pertussis in an Animal Model
Groups of 20 BALB/c mice (females, 5 weeks old) were immunized subcutaneously with ¼ of a human dose (125 μl of vaccine) and were boosted 3 weeks later. One week after the booster, a sample of blood was collected from each mouse for antibody determination. The mice were then challenged by instillation of 50 μl of bacterial suspension (+/−5 106 CFU/50 μl) into the left nostril under ether anesthesia. Five mice in each group were killed at 4 different times (2 hours, 2, 5 and 8 days) after challenge and the lungs were removed aseptically and homogenized individually. The log10 weighted mean number of CFU/lung was determined by counting the colonies grown on Bordet-Gengou agar plates after plating of 100 μl of 4 serial dilutions of the homogenate. The arithmetic mean of the log10 weighted mean number of CFU/lung and the standard deviation were calculated for each group and each time point.
Three experiments were performed. The same vaccine groups were included in each experiment but animals were either challenged with B. pertussis strain Tohama, B. pertussis strain 18323 or B. parapertussis.
The day before challenge, blood was collected from each mouse. The anti-PT, anti-FHA, anti-PRN and anti-BrkA antibody levels were determined by ELISA. The geometrc mean titre for each group of mice was calculated.
Example 12 B. pertussis Strain Tohama Challenge
In one experiment immunized mice were challenged with B. pertussis strain Tohama. The number of CFU/lung at each timepoint after challenge and for each group is summarized in the FIG. 1. The experiment had low variability with the data having a mean square error of is 0.450.
Statistical analysis of the data using ANOVA1 was used to assess the data. No significant difference was seen beween the protection against B. pertussis offered by DTBrkA conpared to control, indicating that immunisation with BrkA alone is insufficient to elicit protection. In contrast, the addition of BrkA to a DTPa-2 vaccine produced a statistically significant increase in protection showing that, in combination with PT and FHA, BrkA can produce additional protection. The level of protection conferred by DTPa-2 BrkA was statistically slightly less than that conferred by DTPa-3 which conferred protection statistically equivalent to DTPw. The DTPa-3 BrkA vaccine provided excellent protection from challenge after 2 and 5 days but less protection after day 8.
Example 13 B. pertussis Strain 18323 Challenge
In this experiment, immunized mice were challenged with B. pertussis strain 18323. The number of CFU/lung at each timepoint after challenge and for each group is summarized in FIG. 2. The experiment showed low variability with the mean square error of the experiment being 0.402. Statistical analysis using ANOVA1 showed that again DTBrkA did not provide an significant protection over the control. However, DTPa-2 BrkA provided better protection than DTPa, showing that BrkA, in combination with other B. pertussis antigens gives additional protection. The protection achieved by vaccination with DTPa-2 BrkA|, against challenge with B. pertussis strain 18323, was statistically equivalent to that provided by DTPa-3, DTPa-3 BrkA and DTPw.
Example 14 Comparison of Protection Against B. pertussis and B. parapertussis in Mice Vaccinated with DTPw or DTPa
Groups of 25 or 30 BALB/c mice (females, 5 weeks old) were immunized subcutaneously with ¼ of a human dose of DT, DTPa or DTPw from different sources (125 μl of vaccine) and were boosted 3 weeks later. The sources of DTPw were Triple antigen (CSL), Tri-immune (Lederle), Pentacoq (MSD), Combivax (Behring), Infanrix (SB), DKTP (RVK, DTPw (Connaght) and Trivax (Wellcome). The sources of DTPa were Infanrix (SB), Triacel (PMCS), DI-TE-KIK (Amvax), A cell-immune (Lederle), Tropedia (Biken), Tricelluvax (Biocine/Chiron), Pentavac (PM-MSD) and DTPa-2 (SB). One or two weeks after the booster, a sample of blood was collected from each mouse for antibody determination. The mice were then challenged by instillation of 50 μl of bacterial suspension (+/−5 106 CFU/50 μl) into the left nostril under anaesthesia. Five mice in each group were killed at 5 or 6 different times (ranging from 2 hours to 14 days) after challenge and the lungs were removed aseptically and homogenized individually. The log10 weighted mean number of CFU/lung was determined by counting the colonies grown on Bordet-Gengou agar plates after plating of 100 μl of 4 serial dilutions of the homogenate. The arithmetic mean of the log10 weighted mean number of CFU/lung and the standard deviation were calculated for each group and each time point.
The day before challenge, blood was collected from each mouse for determination of the anti-PT, anti-FHA and anti-PRN antibody levels by ELISA. The geomean titre for each group of mice was calculated.
Results were analysed statistically by applying 1-way and 2-way ANOVA after assuming equality of variance (checked by Brown and Forsythe's test) and normality (checked using the Shapiro-Wilk test). Differences between groups were analysed using the Dunnet test, Tukey's studentised range test (HSD) and Student-Newman-Keuls test.
Results are shown in FIG. 3, and show that the DTPw vaccines induced good lung clearance of B. pertussis and B. parapertussis. However, DTPa vaccines induced strong lung clearance of B. pertussis but only limited clearance of B. parapertussis.
This experiment demonstrates that antigens present in the DTPw vaccine and absent from the DTPa vaccine are protective against parapertussis. Moreover, the antigens present in the DTPa vaccine, specifically FHA and pertactin, may display antigenic variability when compared to the corresponding parapertussis antigens.
Example 15 Protection Against B. parapertussis by Immunization with DTPw
Protection against a B. parapertussis challenge in the mouse lung clearance model can be obtained by active immunization with a DTPw vaccine (composed of B. pertussis killed whole cells).
In this experiment mice were immunnized twice (day 0 and 21) with ¼ human dose of DTPw vaccine and were intranasally challenged with B. parapertussis on day 28. Protection was measured by counting B. parapertussis in the lungs 0 (2 hours), 2, 5 and 8 days after challenge.
The results shown in FIG. 15A demonstrate that immunization with DTPw resulted in a large decrease in the number of B. parapertussis present in the lung, compared to control mice.
As shown in FIG. 15B, protection against B. parapertussis can also be obtained after passive immunization using an anti-DTPw serum. In this case, 500 μL of anti-Pw serum or normal mice serum was injected intraperitoneally to mice 20 hours before intranasal challenge with B. parapertussis. Bacteria remaining in the lungs were assessed 0, 1, 2, 5 and 8 days after challenge.
As shown in FIG. 15B, passive immunization with antisera against DTPw resulted in a sizeable reducetion in the number of B. parapertussis in the lungs of mice compared to the control group.
Protection observed against B. parapertussis after active and also passive immunization with a DTPw vaccine containing B. pertussis killed whole cells suggests that cross-protective epitopes exist between the two strains.

Outer Membrane Protein Samples
B. parapertussis outer membrane proteins (OMPs) samples were isolated from ATCC15237, using the protocol described in Inf. Imm. 1998, 66(8), 3597. This provided B. parapertussis OMPs at around 64 μg/ml,
Gel Electrophoresis (SDS-PAGE)
Four aliquots of (ca. 13 μg each) of OMPs sample were pooled and evaporated to dryness under vacuum. The residue was solubilised in 100 μl of 0.1% w/v n-octylglucoside in water. The sample was reduced by the addition of 10 μl of 200 mM tributylphosphine and alkylated with 5 μl of 2-vinylpyridine. The reaction was performed at 4° C. for 4 hours. The mixture was then precipitated and washed with the Amersham SDS-PAGE clean-up kit. The complete sample (36 μl) was then dissolved with the SDS-PAGE sample buffer (36 μl) and reductant (7 μl) provided with the Bio-Rad Criterion XT gels. 64 μl of water were added and the mixture was heated at 95° C. for 5 min.
Two gels with lanes loaded with 14 μl (ca. 5 μg) of sample each, were run using a MES (2-morpholinethanesulfonic acid) running buffer to provide resolution for the small size range. Two other gels, also with lanes loaded with 14 μl of sample each, were run using MOPS (3-[N-morpholino]propanesulfonic acid) for resolution of the heaviest proteins. For each gel, on each side of the sample lanes, prestained and unstained standards (BioLabs cat no. P7708S and Bio-Rad cat no. 161-0317) were co-electrofocused as gel and Western alignment guides, respectively.
Gels were stained with the EZBlue Coomassie G250 colloidal reagent (Sigma).
Western Blotting
Immediately following gel electrophoresis, for each running buffer used, one gel was electroblotted onto a nitrocellulose membrane (Hybond ECL: Amersham), using a transfer buffer of 25 mM Tris, 192 mM glycine, 0.01% w/v SDS and 20% v/v methanol at 4° C. with a voltage of 100 V for 1 to 1.5 hour. Transfer was accomplished using the Trans-Blot Cell wet system from Bio-Rad.
Electroblotted proteins were revealed by pool of mouse sera raised against B. pertussis (αDTPw), produced as described in Example 15, followed as secondary antibody by alkaline phosphatase-conjugate goat anti-mouse IgG/IgM. Western immunoblots were visualised using AP chromogen kit nitro-blue tetrazolium (NBT)/5-bromo-4-chloro-3-indoyl phosphate potassium salt (BCIP) from Promega.
Gel and Western Blot Matching
Immunoactive bands on the Western blot membrane were matched to the corresponding Coomassie stained gel band by alignment after re-sizing of the molecular weight markers present on the scanned images.
In-gel Digestion and Peptide Extraction
The bands were excised and cut into pieces (ca. 1 mm3). They were then transferred to 500 μl Protein Low Bind eppendorf tube. The gel pieces were washed three times with 300 μl of 50% v/v methanol and 5% v/v acetic acid in water for 15 min, followed by 300 μl of 100 mM ammonium bicarbonate for 5 min. Gel pieces were shrunken in 300 μl of acetonitrile for 5 min and dried under vacuum in a Speedvac evaporator for 5 min. The dried gel pieces were re-swollen in 100 μl of 5 mM tributylphosphine, 100 mM 2-vinylpyridine and 100 mM ammonium bicarbonate at 4° C. for 1 hour. The supernatant was discarded.
The gel pieces were washed with 300 μl of 100 mM ammonium bicarbonate for 5 min and shrunken in 300 μl of acetonitrile for 5 min. That step was repeated two times. The gel pieces were dried under vacuum in a Speed vac evaporator for 5 min.
In-gel digestion was performed overnight by the addition of 50 μl of a solution of native Bovin trypsin (100 mM ammonium bicarbonate, 5 mM CaCl2, 0.01% w/v n-octyl glucoside). The proteolytic peptide products were extracted by sonication in 5% formic acid and acetonitrile. The combined extracts were then reduced to approximately 20 μl by vacuum evaporation.
Mass Spectrometry
Band digests were analysed by nanoLC-MS/MS using a Micromass QTof-2 tandem mass spectrometer (Micromass) operated by the Masslynx data system (Micromass). The Q-Tof was operated in survey-scan mode using a 1-s MS survey scan, from 400 to 1500 Da, followed by 1-s MS/MS scans on eight different precursor ions, from 50 to 2000 Da. MS/MS spectrum acquisition was allowed for up to a total of 4s on each precursor ion or stopped when the signal intensity fell below 3 counts/second. Precursors were excluded from any further MS/MS experiment for 200 sec. Only doubly and triply charged ions were selected as precursors for MS/MS. The cone voltage was of 35 V. The collision energy was adjusted according to the charge state and the mass of the precursor ion. The mass spectrometer was fitted with a nanospray SilicaTip emitter (New Objective). It was tuned to reach a resolution (fwhm) between 6000 and 8000 at m/z 432.9 (angiotensin). The capillary voltage was set between 2000 and 2700 V. The source temperature was 100° C.
The HPLC system was a CapLC (Micromass) using a ten port-valve enabling on-line desalting. The trapping cartridge was a C18 Symmetry (5×0.3 mm−5 μm−300 Å) (Waters) operated at 10 μl/min with 1% v/v methanol and 0.1% TFA v/v in water. After 8 min the ten-port valve was switched. The analytical columns were Atlantis C18 (150×0.075 mm−3 μm−100 Å) (Waters). They were operated at 250 nl/min at room temperature. An AB gradient was run from 5 to 40% B in 30 min. The eluent A was 0.1% v/v formic acid and 2% v/v acetonitrile in water. The eluent B was 0.1% v/v formic acid and 5% v/v water in acetonitrile. The equilibrium time after gradient elution was of 20 min.
Protein Sequence Database Search
Peak masses extracted from electrospray MS/MS spectra using the PeptideAuto macro were used for protein identification using Mascot 1.9 software (Matrix Science). The interrogation was performed against the protein sequence database of Bordetella parapertussis strain 12822 (4185 sequence entries) downloaded from the Sanger Institue web site (http://www.sanger.ac.uk). The mass tolerances allowed on the precursor and fragment ions were of 0.25 Da. Only proteins for which three trypsic peptides were identified were taken into account.
Results
The alignment of the Western blots and the corresponding Coomassie-stained gels for the two running buffer systems used are displayed in FIGS. 5 and 6. B. parapertussis OMP gel bands detected by Western blotting using sera raised against B. pertussis (DTPw) were excised from the gel. Trypsin was added and peptides were eluted out of the gel bands as described in the Materials and Methods section. Trypsic peptides of each bands were chromatographied by nanoLC and sequenced by MS/MS. MS/MS sequence data were used to search against the B. parapertussis protein sequence database. Hits were manually evaluated for their scores, ion intensity and number of matched trypsic peptides. Gel bands identification are summarised in Table 7.
For 6 MOPS gel bands and their MES equivalents , four membrane proteins were identified:
  • i) bands #8 (MOPS) and #14 (MES): autotransporter (13PP0452 gene);
  • ii) bands #9 (MOPS) and #15 (MES): TonB-dependent receptor for iron transport (BPP3376 or BFRD gene);
  • iii) bands #12 (MOPS): outer membrane porin protein (3PP3392 gene);
  • iv) bands #13 (MOPS) and #18 (MES): outer membrane protein A (BPP3135 or OMPA gene).
The identification of the autotransporter protein (BPP0452−Theor. MW=177 kDa) in gel bands at approximately 60 kDa could be tentatively assigned to a proteolytic fragment or to other autotransporter proteins displaying a high level of homology. This protein is the B. parapertussis homologue of SEQ ID No: 50, sharing 94% identity.
The TonB-dependent receptor for iron transport (BPP3376) is the B. parapertussis homologue of SEQ ID No: 14, sharing 98% identity.
A cytoplasmic chaperonin protein was identified for the gel bands #10 (MPOS) and #16 (MES) that could be associated to a contamination of the outer membrane fraction during the sample processing.
Conclusion
The method identified several antigens which generate an immune response which is crossreactive between B. pertussis and B. parapertussis. The proteins encloded by SEQ ID NO: 50, 100, 14, 106, 108, 110, 102 and 104 are such proteins. The identified proteins isolated from either B. pertussis or B. parapertussis could be usefully incorporated into an acellular vaccine to provide protection against both B. pertussis and B. parapertussis disease.
